What games do you replay regularly/annually? (No shame if you skipped a year or two.) I am especially interested in 'comfort' games.
Only rule is, you should have played the game for the first time at least 5 years back.
My list:
Street Fighter 2 in all variations/on all platforms I have access two. I guess I have been playing it regularly for more than 25 years by now. No Street Fighter after the Alpha/3rd Strike ever captured me like this.
Contra / NES This one I play regularly for more than 30 years (at least), to this day my favorite action game and the ultimate benchmark (I played all NES/SNES/Genesis Contras and Operation Galuga, nothing comes close.)
Slay the Spire: Hits 5 years of being released, I played since the early access and wasted too much time on this, still fun and perfect on smartphones
Doom I/II: I cannot tell you what it is, there are obviously better FPS than Doom I/II, but sometimes, if I just want to blow some steam, Doom is the only thing that delivers. (I think I never played trough all episodes of either Doom I or Doom II
Also, if you enjoy Doom 1 and 2, I highly recommend seeking out Heretic and Strife. Heretic has amazing level design using the Doom engine to create places that feel like towns and medieval churches and stuff. And Strife somehow managed to make Doom into an interconnected world with a decent story.
I'm not big on Hexen - the respawning enemies and the lack of weapons (there's only 4, technically 12 but you only have access to 4) bugged me.
