Attak by JohnnyTwoShoes[0,1], is one of the standout games from that era: super-saiyan type battles using an underlying physics/ragdoll engine with fully destructible buildings and terrain.

Half the strategy was digging out an underground bunker to shield yourself from your enemy's 500m vertical drop attacks. It was an incredible feat of programming for the time.

The game unfortunately is in that final tiny percentage of AS3 games with missing features and thus does not work with ruffle yet, I suspect because the game was so cutting edge.

There's honestly a ton more, you can download the archive and go through the various community lists in there. I've spent a few evenings just having a few drinks and playing some old games! :D
