I say if you are undecided, don't release the code! Cause, once you release it, it is too late to go back, while, if you decide later that is what you want to do, you can reverse the decision of keeping it to yourself.

Ultimately though, ADOM is essentially a completed game and something to definitely be proud of! Its been one of my favorite games for over a decade and I still play it to this day. Sure there are some minor bugs left in it, but, none of them are remotely game-breaking.

I'd hate to see ADOM's good name get tarnished by a plethora of cheap knock-offs, silly/stupid mods and whatnots.

Concentrate on JADE and getting another great roguelike game out there! Besides (correct me if I'm wrong here), I thought you were intending on releasing the source to JADE anyways, there's little point in fracturing your development time and the development time of the community into two groups.
