Summary: Don't let the arguably low score scare you, this game is a jewel. It's just hard to find that jewel, as the game is very counter-intuitive. Which is not the developer's fault but just the nature of time travel.
Summary: Many of the poor critic ratings, I believe, were written back when Achron was still under primary development. I'd compare it to tasting a cake that's not done cooking yet - of course it's not going to appeal to many people.
Summary: this game is bad broken path finding and a the AI has a significant lack of the I and if that wasn't enough you have to remove moves made in the future if i wanted to do those moves i wouldn't have changed my moves in the past would i
Summary: This is, as I write this, most likely becoming my second favorites strategy game after Starcraft Broodwar. Let's put it straight first. For me real time strategy games is all about multiplayer. So I don't care if the campaign of this time travel extravaganza is supposebly weak.
Summary: Never, anywhere, have I played an RTS as involved as this one is. Simply put this game is a must buy summed up in two simple words: TIME TRAVEL. I mean real honest time manipulation mechanics that allow you to not only "fix" your "mistakes" but also bend and break real time to your will.
Summary: Quick Info: If all you like to do is playing skirmish and single player, then Achron is a very clear NO BUY for you. The Campaign, while actually having an interesting story, is heinously and VERY effectively murdering any fun you might have had.
