In my experience it's pretty much for everyone with any interest in board games. For most games there will be an erklärbär (someone to explain the game) and several tryout tables. I've only gone with a small group so far but there is certainly always room for 1 or 2 players somewhere as well, you'll need to be open playing with strangers in that case but generally it's nice people.

The games featured are everything you can think of and more. Last year I spent at least 20min building marble slides at one of the stands but also played 1/3 of a rather complex game, where 1/3 took 45min. We also played 2 rounds of the magnificent party game SoKleever. +at least 10 other games

I would consider it if you can imagine yourself spending a day(or a few) just playing boardgames and strolling along.

The intimidating thing for me is more the setting of a large trade fair, especially if you've never been to one, certainly it's not as bad as gamsecom in Köln, but it can definitely be pretty crowded.
