This game is essentially TA2, anyone who played the original can confirm this and will find the game very accessible because of it. It has a lot of really good features that make it a worthy successor to TA.
The zooming map is impressive and although it takes some getting used to, and does have the downside of not giving you a mini-map, it really does function well.
Unlike some games that go resource crazy, the whole resource system is tied in tightly to only two resources Mass & Energy. Mass is the limiting factor as its sources are are few and far between, although it can be converted from Energy giving an ultimately limitless supply.
The super-units are very impressive to use although building even one takes a huge amount of resources and time. Once one is walking across the map however, you can see its effectiveness as it wipes out entire armies!
The only failing I have noted during recent online games is that it is possible to rush and overpower an enemy at the start as defences are so slow to build. I am sure they will solve this in future updates and overall it does not stop this game from being an instant classic.
The best RTS for years, if you love RTS it is an essential purchase!
