BotArena3 Innovated RoboForge!
The concept is not really original. I've always wanted to do something like this but still, with a little tweaking, you made an all-out original RoboForge.
Perhaps, try to let players create maps. Also, add some obstruction in the battle field so it's not as boring as a simple 4-cornered ring.
Overall, I ended up playing for 3-consecutuve days from my coffee breaks.
