Makes a superb game even better.
New heroes, units and buildings with awesome graphics, great sound effects, nice voice acting and the deep warcraft universe. The strategies will change a bit from RoC to TFT, giving some more balance to the units. In short, Blizzard added anti-air and anti-magic units so just mass casters or mass air units won't beat almost everything, and if these new counter-units are used well, they can give you the victory.
Four selectable races and different strategies that will need different heroes and units give this game a huge replay value
Tho most annoying aspect of the game, a crash to windows desktop now and then was actually fault of my PC and low-cost RAM, so since it has never happened again, i love every bit in this game / expansion.
The Bottom Line
Roc + TFT is the best game i have ever played. Since I bought it, I have finished the campaigns and played literally thousands of online games. Every time the game is about to start, the players have been picked, the team defined and the map is loading, I know that shall my team win or lose, I will have a great time
