Brilliant idea, having a game for an old system that half of today's handicaps (ex. you) have never even heard of.
If you mean stuff like LEGO Star Wars, NO. LSW was extremely boring halfway into a level.
They sound like friends.
Of course Badspot would be in a game about HIS GAME. Also, "ideal characters"?
tl;dr get out.
you have my respect now
if your going to make a video game about blockland, it would be a bit harder
make it on the 360
make it so you have objectives
make bots w/ timers to lay down bricks that can get in youre way, but are actually builds
then you wont be fully stealing the game, but you also wont have to worry about keys and stuff
