I'm familiar with it, but didn't play it much myself. That's cool that you made tournaments/championship events and stuff. That sounds like fun.
A classic game I think people kind of forget, is RoboWarrior for the NES. I remember getting it from a thrift store when I was a kid, and I remember loving the cover art. I never played it for too long, as I couldn't get very far. It was kind of like bomberman, in that you needed to clear a path to get through the level and you have to use bombs to clear said path. But, there are enemies who are in your way and I thin some that can go through obstacles to get to you. idk, I need to replay it soon.
