Ages ago most Sonic fan-games used the platform movement or were non-sonic styled games. A big revolution happened when the Static Engine became popular, influencing every game that came after it, raising the standards to another level. But the last revolution was when the 360 engine was born, it evolved to the point that now we have an engine almost 1:1 to the classic, used by half of the fan-games nowadays.
But what's going to happen from now on? I've seen some posts here commenting about how most of the fan-games became Sonic Worlds with different graphics with no innovation.
That brought me some questions that I would like to know other people's opinions... Does the classic style needs innovation? Are people bored of the classic gameplay? Copying graphics, game style or other things from the official games is a bad thing? Does the standard raised so much that a hobby like fan-gaming became too hard to conciliate with real life, so that nobody finish or work too much in their games? What do you expect to see in a fan-game nowadays?
Except for a full game, I guess we all already expect it!
