Syndicate from 1993. Don't know if that fulfills the "RPG" part of Tactical RPG but it's definitely worth a play.

UFO: Alien Invasion.

A free, open source reimagining of the original XCOM games.

XCOM 2 - Steam

There was an old one on the first sega console controlling different knights on a board. It was the first game of its kind i played but could never remember what it was.

Another good one that’s more recent is Triangle Strategy. Positioning is important. Great story. Very similar to FFT but FFT is better overall. Still a great game and more modern.

I rather enjoyed Gears Tactics a few years ago.

Advance Wars, of course.

I haven't seen any mention of "Steamworld: Heist", yet. It's a very different sort of game engine, but scratches the same itch.

I'm playing Last Spell right now, isometric base defense game. Lots of viable ways to play, but later missions become a slog if you don't plan out hero builds. A run takes 5-10 hours, but rounds take 20 minutes. Emphasis on crowd control and positioning.

Darkest Dungeon is nice if you want a break from isometric stuff, dungeon crawler, emphasis on team combat and resource management.

Creeper World III if you want to try RTS style, lots of community maps.

Tactical Breach Wizards, Come in through a window, throw everyone else out the window. Silly, but fun.

Laser Squad, playing couch hot-seat is what sent me down this path.

I really liked Jagged Alliance 2, Afterlight and especially X-COM: Apocalypse. Apocalypse had such radical departures from the first two Ufo titles, which did not make it very well liked among enthusiasts, in particular the real-time battle mode. But the game had such fun mechanics and steep difficulty curve, I really enjoyed the challenge of it, as opposed to getting another Enemy Unknown clone that was TFTD.

If you enjoyed Into the Breach, take a look at Tactical Breach Wizards. Not much of an RPG, but the combat is similar to ITB. Not as difficult though.

What's the one in the picture? Also, how do I read alt text on Summit?

Fallout Tactics remains my favorite Fallout.

Final Fantasy Tactics Advance, above all else.

That being said, Shin Megami Tensei Devil Survivor 1 and 2 are awesome. They combine SRPGs with the usual SMT combat - I don't think I've found something similar yet.

You move around like you would in any other SRPG, then you can attack enemies in range to enter normal turn based combat - however, at most, you can only play out 2 full turns before combat ends. Afterwards the next unit moves. Each unit represents a squad of up to three characters you will be batteling with, usually a human and two demons. Depending on your squad, you may have different movement, range and abilities.

My favorite series is disgaea, but I wouldn't recommend it to most people, it's over the top game breaking silliness.

Chroma-squad is often overlooked, but captures a lot of what name 90s trpg's great and improves on the formula quite a bit.

The absolute best trpg imo is "bionic dues", I feel like it you enjoyed into the breach you should definitely give bionic dues a shot, it's such a different style of game,

I love Tactical Breach Wizards, which is somewhere between Into the Breach and Invisible Inc (also amazing).

Shining Force is a classic. Basically Seva's answer to Fire Emblem.

Wargroove is pretty good too. Kind of like Advance Wars, but in a more medieval fantasy setting. From an indie dev with pixel art. My only real complaint is one I have with all modern "retro pixel art" style games: the "pixels" can move by much smaller increments than themselves. I wish games that used that style would align everything, including animation, to the fake pixels. It looks kind of busy and messy imo. It doesn't bother me enough to ruin Wargroove though.

Banner Saga was pretty good. It's a combination of tactical RPG with mostly text-based choose-your-own-adventure style elements between battles. Still haven't played the 3rd one, but I enjoyed the first 2.

Not my all-time fav, but I like it a lot and it's kinda slept-on: Tom Clancy's Ghost Recon: Shadow Wars for the 3DS. It's got a lot in common with X-COM -- heck, Julian Gollop was even the producer on it.

Not my fav by any means, but I've really been enjoying the Kriegsfront Tactics demo this week.

Jagged Alliance 2 (especially with the 1.13 mod) is the most ludicrously detailed tactical RPG you'll ever find. It can be a nightmare to actually play until you spend many, many hours learning all its systems, but nothing else comes close immersion-wise. You can customize every mercenary's loadout down to individual weapon attachments, capturing different parts of the map gives bonuses that actually make sense (like being able to ship in weapons once you've taken the airport), you can train militias to hold onto captured sectors for you, and you can even use the in-game internet to send flowers to the main villain.

I'm a weirdo, so Massive Chalice.

It has a strange high-concept premise where you are an immortal ruler defending against a monstrous army that only attacks every decade or so. Any surviving individual squad member will only be able to go on a handful of missions before aging out, so you are also managing familial bloodlines to birth new soldiers, while controlling for genetic and social traits that get passed down. I love the uniqueness and big ideas. It's far from perfect, but you asked for favorite not the best.

Wasteland 3 is really good, baldurs gate 3 kinda, darkest dungeon, Valkyrie chronicles 1 & 4

X-Com - UFO Defense and TFTD are definitely my favorite. Fallout 1&2 are a close second and I've been meaning to play through them again. Ogre Battle is a distant third, with Front Mission right behind it.

Wildermyth was very enjoyable, it's not as deep and well written as some of the others mentioned but still held my attention long enough to finish it.

Pretty unique art style and it felt relatively challenging throughout.

My favorite is the original Final Fantasy Tactics, hands down. I also liked XCOM 1, Advance Wars, Ogre Battle 64, Unicorn Overlord, Fire Emblem 3 Houses, and probably a few others I can't think of right now.

Tactical RPG's are my favorite genre of games, and Tactics Ogre (not Ogre Battle) in any of it's many iterations is my favorite. No game is perfect but it does so many things so, so well. Matsuno's magnum opus. The latest version, Tactics Ogre Reborn added high quality voice acting which I really love.

FFTactics like others was my favorite.

I quite enjoyed into the breach.

I bought a couple of tactics like games on steam and they all dont seem to be fun to me. I guess I like to grind a bit on fair but punishing tactics titles.

I like the disgaea series not only because of the deep systems involved, but also just because gameplay is so snappy. So many SRPGs are slow as molasses in terms of interface. I also really enjoyed Unicorn Overlord recently.

Just can't beat The Shining Force games. Can't.

My favorites are probably the Disgaea series and related games (Makai Kingdom, Phantom Brave) and Tactics Ogre. I also like Tactics Ogres more popular little brother, Final Fantasy Tactics.
