SunAge is awesome! Don't listen to the naysayers...
I've never had the inkling to write a game review in my life. I like to read them, like you, in order to determine whether I might like a game or not, but I've never taken the time to contribute. Until now.
First, I can't believe how poorly SunAge scored with Gamespot. It simply does not deserve it. This game is genuinely fun, addictive and, at its latest point of evolution, smooth-running. Although I don't judge a game by graphics, they are great in this game. Gameplay is what's most important to me, as is story, and though there is not a campaign per se, each map has its own story with pretty decent voice acting and lots of action. I find the interface very easy to use and quite intuitive. Some new things such as right clicking for specific targets or squad/unit info, and being able to switch to an alternate fire/special ability mode for units as well as upgrading them greatly enhance the gameplay and make it unique. I love it!
For people who compare this game to other RTS', well, go ahead if it makes you feel good. I bought this with no expectations but was drawn to the notion of one guy working on this by himself for many years with a gaming passion to bring something to the rest of us gamers. Well, he really delivered! Honestly, this game is really, really fun and really, really well done! You have to try it for yourself, approach it with an open mind and resist comparing it to other RTS games. It stands on its own solidly by its own merits. I wholeheartedly and highly recommend this game. If you can still find it, pick it up right away. You will not be disappointed.
