Overall, Eterium was a pretty fun game to play. It definitely nails a lot of its design goals to bring back the feel of Space Combat games from the 90's and while some aspects of the game are off-putting to some (The horribly stock/generated looking Anime art) I don't think it really detracts from the overall experience; unless you personally have a stick up your ♥♥♥.
The combat is fast paced and exciting, and with the multitude of control options now available, people really have no excuse not to give the game a try. It can feel a little "stiff" at times, and it does seem like no matter what craft you fly, you might as well not have shields at all compared to the enemies, but it makes it all the more sweeter when you score that final kill to complete a mission in a banged up ship that is 1 hit away from exploding.
The story overall is certainly not unique in that it has been told countless times before, in many different forms, but I still think the story is passable and has some very interesting moments - this despite the bland and generic conversations between characters. My only real let down was that near the end the story wraps up too quickly, almost unexpectedly. They really could have gotten another 5 or 10 missions out of the final story-arc and it would have been great to see that fleshed out more.
For what the game costs, and what its stated goals are, I think the product delivers on every level. Wait for a sale if you must, but do not neglect this game if you are longing for that 90's space combat experience.
