Couple days ago I bought that alien versus predator classic 2000 thing.. And that was the only game that day that didn't give any trouble. And playing with marine, I screamed like a girl when alien jumped suddenly towards my face.

It's nice to share things. Got that of my chest so what now..

What is better SPaZ or Gratuitous Space Battles? I tried demo for both and both seemed like nice game to me, but which one is better?

SPAZ is better for sure.

I don't think you can really compare both. Gratuitous Space Battles is a kind of tower defence game (sort of), SPaZ is more like action-adventure-strategy.

I know but how to decide otherwise when I like both and can grab just one? :(

Sacred 2: Gold is $20 on Gamersgate and I want to purchase it but I got a question. Multiplayer servers are still online for Europe and it is crowded as well? Thank you for the answers.

Multiplayer's pretty much dead, though you might get some people to join you on a play session in darkmatters:

I am interesed in this even without the multiplayer though, but GG won't sell me Sacred 2. Do they allow gifting?

Yes.

If you're using Windows 7 be prepared for a lot of annoyance. The game does not like Windows 7 and installation will be a pain in the ass (for one thing you will need to reinstall any Phsyx and Open AL drivers you have as the game will corrupt those when it forces the installation of outdated drivers).

Another matter.. Antimatter.. I bought bloodlines from steam.. I tried it once. That SOB just closed without anything when playing. Perhaps it was widescreenmod or that unofficial patch. I didn't remember that being so old that it would not support widescreen. =)

Install in a VM, and then copy paste the game's files?

Good luck with that. As I said, that was just one of the problems. Another will be finding the correct patches and getting those to play nice too. Last time I tried patching, I had to each one in safe mode and they took several hours.

Really, I'd avoid the game if you're not playing it on XP.

Does that mean that downloadabple xp-thing or what?
I kinda understand the term virtual machine but..

An OS into an OS, something like that.
