X7's problem was trying to mix 2D with 3D. Which resulted in the 2D sections being terrible, and the 3D ones suffering from bland and uninspired level design... The only halfway Descent level was Stoneking's really, and the 3D cyberpsace maze is only worth a damn because the right side up-upside down shenanigans make it more interesting. Axl wasnt the problem, although his gameplay WAS little more than X minus the charged shot. and His copy Shot took WAY too many hits to actually kill an enemy, and you still had to charge it to shoot. X8 pretty much fixed Axl's gameplay, and made him much more fun to play, but X8 was a Sidescroller. And it didnt have the greatest level design either.
Also Legends is good yes. But that's not the kind of 3D game im talking about. Legends is a 3D Dungeon Crawler/actionRPG game. the mega man franchise needs a good 3D platformer game. (Something X7 failed to really deliver on as well)
Something... like the X Buster quake mod.
XB2 - MegaMan mod for Quake 3ITS NOT THAT HARD, CAPCOM, COME ON.
Although a MegaMan MMO is a novel and interesting idea. a 2D MegaMan MMO no less, but an MMO still.
