There've been a number of reviews stating the game was constantly crashing, even some recent ones, but I took a deep breath and went and bought it during the sales. I'd enjoyed Genesis, the original game, and liked the idea of the broader range of units and buildings in the updated variant. Anyhow, the game has been stable for me, with not a single crash in 8 hours of play now. - I've had two 'exception faults' after closing the game, but the gameplay has never been affected. But I love the game. I love the look, and am just about getting the hang of the revamped building screens. It plays much slower than the original, and that's another bonus for me. Great game, but I'd get it in the sales just to be safe. - I think I'm right in saying that if it's unstable on your system, GOG are one of the few reputable companies who'll give you a refund, no questions asked.
