Stalker: Call of Chernobyl Modification

It's basically heart attack simulator when you put on increased damage and do an ironman playthrough, very fun.​

Call of Misery is another good one.
CoM last day is also really good.
All are highly unstable though. Best to play the game with a backed up file.
