I know the feeling - one has too many idea's to all turn them into reality. But it shouldn't discourage you to go 100% after one idea and leave the others alone for a while 
Yeah, I'm just struggling to want to open an IDE at the minute though.
My new direction is mostly a change of genre: "construction and management simulation" is the genre officially called I think. I also decided that it will not be an opensource remake of a game. I can probably write a whole page about it, but it would be very offtopic here The biggest challenge is to keep the whole thing achievable.
Well, I for one would certainly like to hear more, so if you want to start a new thread, PM me, or point me to a link...
ontopic: I don't know a lot about apoc, only tried it for a few minutes, but wouldn't it be possible to get apoc stuff into openxcom, so have an openxcom slowly transforming into apocalypse? They can't be *that* different from eachother that you would need to start from scratch... Just putting graphics aside and only looking at some gameplay aspects for example.
I think the biggest difference with Apoc is the geoscape. You also can raid buildings regardless of alien presence. You can also destroy buildings in battlescape and it'll destroy them in geo.
There's also a lot more economics to the game - ie, if you manufacture a lot of an object, it's value decreases; you have relationships with various organisations.
Battlescape also supports a "real-time" mode, not that that would have to be implemented immediately (or at all, unless you're a perfectionist)
That said, I wouldn't rule out the possibility of merging apoc into OXC.
