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. I can relate to some of the reviews because I too thought the game wouldn't work properly, as there is nothing more frustrating than giving out complex orders only to find your army somewhere else entirely because you forgot that one a-move you made.
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. However, now that there've been several patches and fixes, I find that most of the critic reviews won't hold against actual experience. The time travel mechanic is interesting.
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. I learned the game by watching casted games on youtube, and I suggest you do it too!
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. The skirmish AI is incapable of dealing with any player on a pure rts level, add in time travel and it goes under like the titanic.
