Touhou Artificial Dream in Arcadia. Sort of a recent fangame title, by today's standards, but if you're looking for some cool mid-to-late-1990s-inspired PC dungeoneering action (Shin Megami Tensei being a heavy inspiration), it's currently at ninety-two percent off.

Can someone recommend some good 3-player games? Already bought Aliens: FE and I'm sick of Apex and DOOM.

I picked up scribblenauts unmasked for like 90% off, I've always loved the series (though I find unlimited has fewer puzzles...)
