Hi, lately I've been thinking a bunch about Phantom Crash, which I played on an XBox. It was a mecha battle arena game. It had two main modes (three if you count skipping through interminable conversations with NPCs). First, you'd take your mech into an arena and blow people up. Then you'd go to your garage, spending your winnings on upgrading your mech.

The degree of customization you could achieve was striking. There were big options like wheels / legs / hover platform, and a variety of energy / mass / missile weapons. You could get different aim assist chips that had meaningfully different characteristics. You could tune almost any piece of equipment to be lighter or heavier, and a heavier gun really felt more powerful in the arena.

TBH the actual combat was only alright, but we loved the game anyway.

Are there any other games out there that have this kind of feedback loop? Playable today is best, but I'd also go down an internet archaeology hole.
