Funny how I have a quick moan about Beats of Rage yesterday only to find OpenBoR today. In fact I had mentioned OpenBoR before on this site but forgot plus these days they seem to be a little more organised. Saying that, borgeneration.com seems to have a few issues (forum down, mod links 403).
Beats of Rage is an old school arcade beat em up game, and there's various mods for it such as Double Dragon (what a game that was, eh!?). OpenBoR is an open source effort to provide a free engine compatable with Beats of Rage. I'm hopeful that OpenBoR will run with more success on my Linux laptop than the official BoR game does.
The BoR community seems to be pretty active, and there's lots of mods. If I had the time I would try out a few. But I don't.
Just to prove that Wikipedia isn't all that, it mentions OpenHOR - supposedly a subproject of OpenBOR that allows modders to create horizontal and vertical two dimensional aircraft shooting games... really? I think not.
I wanna post more but I am out of time... I'll just note that I'm going to add a translation tool to the site (some cool JS hack I found on another site) among other things and that the completion of the games lists is put off for a few more days because I'm too busy with real work (had to do it some time). Ciao for now.
