What makes it your favorite? Do you want to play it? If so, what's keeping you from doing it?
For me, it's Burning Wheel.
I bought it purely based on aesthetics back in 2008ish, then got the supplements, then Gold, then Gold Revised, with the Codex, and the anthology...
I blame it for my weakness for chunky, digest-sized, hardcover RPGs. :P I also like the graphic design, I like the prose (even if it's divisive), and it has both interesting lessons you can plug into other games (like "let it ride," letting success or failure stand instead of making lots of little rolls) and arcane systems that pique my interest (like the Artha cycle, which makes roleplay, metacurrency, skill rolls, and advancement all intersect). I genuinely like reading it for its own sake.
I haven't played it because... well, since it's not D&D, that immediately makes it harder to get people interested, sadly. It's also a bit daunting, given its reputation as a crunchy system. But I have a group of players interested in trying new things, and fewer other games calling for my attention, so hopefully I'll get a chance soon. :)
Persona 5 looks amazing. So does dragon quest 11. I must play all games In a series in order. Its... and autistic thing I think but like, I really can't bring myself to play a game if I haven't played the previous... so persona itself was a spin off of the main shinmegami tensei series, which itself was a continuation of the megami tensei games. I played and beat megami tensei 1, megami tensei 2, and am currently playing shin megami tensei. The original persona was a bit hard to get into but now that I've played the predecessor I'm looking forward to playing it properly after I finish shin megami tensei 1 and 2, I think that's about the time persona started. Shin megami tensei 3 nocturn also looked cool and I'll be ready to play that one as well after SMT2. Soul Hackers 2 looks cool too but I have to play devil Summoner first which doesn't have an English translation, so I'm having to play it with Google lens which is slow going cause my Japanese isn't really that good.
I'm also a completionist... playing dragon quest 5 currently and I'm in the final dungeon and only have TWO monsters to catch but goddammit the Hyperanemon just WILL NOT JOIN ME. I've spent something like 12 hours trying to get him. Probably more. I sat on the entire plane ride from Baltimore to LA for 5 hours grinding the same battle over and over and didn't get him, and also watched several marvel movies. Frustrating... but everything I think, just go beat the game and move on, I'm like, but this is the second to last monster and I'll have them ALL.
Edit: God I wasted so much time. Thinking about it again, I did a search and found out you can't catch the Hyperanemon on Mt. Zugzwang, only in the post game dungeon. Fml.
Cool, however this is a community for tabletop roleplaying games.
Whoops. My bad. Well my top board game pick is Gloomhaven. I even bought it, and my friend bought the stickers and we were gonna play it but instead she just played it with a different group and I never got to play it, even though I payed for it, and not too long after we had a falling out and I find it hard to justify spending another $100 on it.
