I played a ton of Mechwarrior 2 (ATI 3D Rage Edition) - the Aptiva bundle version - and didn't notice it being buggy.... Maybe this is a later version and earlier versions were more buggy?
My own experience was with the 3D-enhanced version of Mechwarrior 2: Mercenaries, specifically. It is possible that the equivalent version for Mechwarrior 2 was more stable. It's also possible my 3D drivers of the time were the cause of the issues I had, but Mercenaries was sufficiently buggy in all sorts of other ways (even the DOS version loved to crash) that I always just blamed the game.
