When I started playing GTA Liberty City Stories I practically didn't stop. But then, college jobs needed more attention and I was losing my rhythm. Result: I couldn't finish the game yet (but I'll do this one day, haha!).
Something always seems to come up. I have no hope of finishing any GTA game( at least not in the near future). Because there is a ton of really good games out right now.
I bought that game when it was released back on 2005 or something, and kept in my library. Installed it last year and completed 100% as a retro I think there was a bug when it was first released.
