So, all versions should be compatible, not sure only about Steam. More exact info will appear in a week.

The way it's often worked (in my experience) is that Steam only works with Steam. It happened with Dragon Age: Origins - Awakening from BioWare, most/all DLC they offer and so forth.

The reason is, I believe, that Steam-bought/based games install in the Steam directory and I *think* they install slightly differently, but I could be wrong. Either way, trying to buy a programme that requires another over Steam doesn't work because it "blocks" you from purchasing it. An example would be the Modern Warfare 2 map packs - You can't buy them without Modern Warfare 2.

I'd be interest in buying Crossworlds from Gamersgate, and I have both KBTL and KBAP from Steam. It would be very nice to know what dev guys think about it - and better don't ask Valve/Steam guys, because it's clear what would they say :)

From my experience Steam games usually are not compatible with other games, be it patches or DLC, but there ere exceptions. For instance, Steam version of Swords of the Star can be patched with at least one of the patches intended for another digital distribution (GG it was, I think). It can be quite important, because Steam is usually very late with patches.

I would suggest you buy the GOTY edition from Gamersgate (US $27). I've never had a single problem with this company.

Most versions of Crossworlds will check for AP on your PC during installation automatically or you'll be able to point the appropriate folder manually. In this case I do not see the problem in installing different versions on Steam one. But we do not know yet how the Steam installer will work and if it is compatible with other versions. Just let us check this question and will post the answer ASAP.

I have preordered from GamersGate. I try to aviod Steam, but CIV V will be a stern test...

At Impulse I just bought a THQ bundle. For the price of one full game I got 17 games. That is pretty sweet. Among them was SupCom FA which I was gonna buy anyways.

Only english version? im from Spain...

Don't you study english there in spain? I'm from Finland so my native language isn't english but i have no problem about the game (like all games) not being finnish.

That would save me troubles for sure, but that would be also more expensive, and I've never bought from GG in the first place so am not sure about service (for comparison I've got almost 200 games in Steam and some experience with that). And it seems I'm not the only one interested in buying GG version to Steam base, I saw questions about that possibility on some other forum or blog :grin:

Saiko Kila, why do you want to buy Crossworlds from another vendor if KBAP and most of your other games are on Steam? Just curious.
