I remember playing Beats of Rage on the Dreamcast. Did people use that engine to make more games or something?
Golden Axe Myth looks kind of cool. I'll have to give it a try.
I'm also familiar with the SOR remake, which is excellent.
Also, did you know: the team known today as Treasure started out making beat-em-ups for Konami (TMNT, Simpsons, X-Men) but quickly split off to create their own company.
