Just found this, why haven’t I seen it before?
Looks to be the successor to Slick, for instance here is sample rendering code, in the J2D-ish style.
Also has BasicGame, etc.
It’s not super mature it seems, and it’s not 1.0 yet, but I thought I’d share as it’s relevant to some people’s interests here I expect.
If there is a better board for this topic then go ahead and move it.
