• Breath of Fire 2 (SNES): I don’t know how I managed to finish this game. It’s too drawn out, didn’t have an interesting story to follow with meaningless and annoying stuff to do and the random battles was too often.
• Killer Instinct (SNES): I played this game seriously, learning the combos and fighting competitive with a friend. But nowadays it just does not feel good to play.
• Toshinden (PSX): Similar to Killer Instinct, I played this game seriously with a competitive friend. Playing it today, I just can’t do it.

The previous Civilization games are playable on Linux, so its not really locking out Linux users. But I guess the online part does not work? I never played in online modes, so didn’t lookup or knew this.
