there were sidequests in the game? i don't remember that at all. i remember the fire dungeon and that giant robot and the stupid train level that i got stuck at. stopped playing after that.
sometimes the quality of a game will drop if the company in question has too many games in development at once. legends 2 was in development at the same time as x5 and probably some other games as well. this also happened with 4 final fantasy games on the psx and 1 on the ps2. ff7, 8, 9, 10, and tactics were all started development at the same time, and the quality varies greatly between the 5 games. and it seems like the ones that come out first have the most problems.
