This is an offer of Warbirds, a very strange "dieselpunk" RPG from Outrider Studios. It's only available for one week, ending on August 31st
( Warbirds )At a quick look the rules are well-presented and it looks reasonably playable, if somewhat complicated. The setting is truly bizarre, with islands floating in mid-air and most resources mined from the atmosphere (think the flying mine in The Empire Strikes Back) - since you really don't want to live near the nastier parts of that there are tankers that supply the islands, and of course flying pirates. It's interesting, and looks like it could be fun if you like combat-heavy games. And the alternative settings are worth a look if you don't like flying islands! It's cheap, and if you want to try something unusual I think it's a good choice.
