JSRF an underrated game but I loved it, the tricks the art the music and even the story was enaging and I cant tell you the satisfaction of doing multiplayer with a friend or siblind and kill the enemy players in the funniest ways possible.
I have been begging for a sequel ever since that game came out
Blinx 2, even though there was quite some negative reviews for it the game was a challenge, fun, the co-op mode required actual team work and the multiplayer was made of absolute awesome. Too bad they discontinued it
Other games as well but mentioning them will require thinking something I am currently set against not doing.
