Name a terrible game that deserves a sequel.
IMO Shadowrun could be an epic multiplayer game if the devs are given more time to flesh the game out. The original game had such awesome ideas but lack of balance, rank, and good connection had kept it from reaching its potential. Games like Halo Reach tries to mimic shadowrun in some ways like jet pack (a la glider) but it doesn't even come close to the amount of fun shadowrun was.
Even with its flaws Shadowrun was still a fun game. If there was a sequel made I can see it becoming the next cod or a classic like counter strike.
