Jedi Academy

Yes, it is Star Wars Jedi Knight: Jedi Academy. I thought classroom and Luke Skywalker will make it easy. Luke is the teacher with robot hand :)

The other hints were:
- plans of the Death Star
- color lightsabers
- X-wing maneuvers lesson.

Another character.

I've no idea. Is it a beat 'm up?

Interesting.
The first drawing made me think of Dynamite Cop/Dynamite Deka because I vaguely remember a fight with chefs.
But the second one throws that guess out the window.

It's mostly a fighting game like Virtua Fighter or Soul Calibur. Mostly.

I'm having a wild guess here - I know that a chimera was indeed in Mother 3 (EarthBound series, 10/10 all of them) and when you mention Soul Calibur I think of a multiplayer fighting game in 2D. Placing these two together leads to one game; Super Smash Bros. Brawl, since it has a level from Earthbound, and if my recollection is true (it was a while since I fired up my Wii) then there was indeed a chimera there, altough rare.

So my guess is, Super Smash Bos. Brawl? just a wild guess :D

No. And its a 3D fighting game. Like Bushido Blade... but with less blades.

I wish I had more time to draw more hints. Instead, here's something I drew a few years ago. This character is also in this game.

Is it Ehrgeiz: God Bless the Ring?

Yep. Your turn.

Why was the cloud marked in the last picture?

Because that's the characters name.
