Spore was never very stable, is it known if the Gog versions is more stable or not?

Save game is ok, or risk of corrupted save?

The only real issues that I've had in terms of stability is I'm unable to maintain a stable connection with the EA servers as I play the game. I've gotten annoyed as well so I manualy download 1000+ of other peoples creations.

Save game is okay from when I had last remembered to save. The game doesn't autosave at all.

Just for info: you already tried to run the game as admin, win xp compatibility mode and so on?

The creature phase is pretty crash-prone, but the rest of the game has been fairly stable so far.

Yep, only crashed in creature phase. And only when I died/respawned. Not the worst stability -- but an irritating one.

I would say the stability appears worse. I've had a few crashes already, and they're completely random :s

The creature phase is indeed very unstable when respawning. But I also discovered that this only happened when I clicked the green checkmark to continue. When pressing the ESC button it never crashed.
