What offline games you played so far and managed to finish them? I finished: Heroes of Might and Magic III (offline campaign) , Dungeon Siege 1, Dungeon siege 2, Stronghold, Legacy of Kain: Blood Omen and probably many others but I forgot over time.
I am not super excited on playing offline games as most of the times, the goal of competing against others online are not there. I focus on online games rather.
It's not too often that I play offline games anymore. I always remember as a kid offline games were all we really knew but now that we are able to play online games, going back to offline games is something I do very rarely.
There is something about playing against others online and competitively that makes gaming so much better nowadays.
