Engaging enormous engines of war in battle should be more difficult than this.
For starters, unlike the original it is difficult to run short of mass and energy - the two resources needed to power the production of units. This is coupled with the emphasis on upgrading a few core units, rather than producing, and memorising, a plethora of the-same-but-a-bit-different tanks. I still remember now an old friend telling me, during a mutliplayer of medieval total war, that he intended to build his army from as many different, and obscure, troop types as possible, thus as to ensure that I didn't have a clue what I was fighting, or how to counteract it. Such beardiness has been devastated in Supreme Commander 2.
Instead what you have is an engaging game that allows the easy(ier) building of experimentals - skyscraper robots capable of destroying an army single-handed. Their names are as ridiculous as their power - King Kriptor, for one!
Admittedly, if you had dedicated a substantial amount of time to perfecting your build orders to the second, then this game will frustrate you. If you had an inherent knowledge of how the dozens of different basic units counteracted each other, then this game will feel like an imposter. Indeed, the smaller maps (often strangely cramped due to extra scenary) will tone down the epic feeling for those expert at the original.
For me, though, it is perfect. Having stalled on the tutorial for several months, I managed to give the game a morning. In those few hours, I had won skirmishes will all the sides (which feel, and look, genuinely different), unlocked all the experimental units and progressed in the campaign. I have tried some multiplayer, and enjoyed the epicness of it all (something served by an incredible soundtrack.)
For those on PC, this game has also regularly dropped to £2.50, which is a farcical price. You simply must own this game for that amount of money. Very incisive descriptions of why the game feels 'broken' to the experts of the original exist, but suffice to say that if, like me, you play many different genres, this is a wonderful addition that allows you 20-60mins of intensely satisfying RTS at a time.
