this good-old RTS game is truly a masterpiece
but the most exciting and addictive RTS game i'd ever bought is this (beside WiC), the campaign is good, the skirmish (random map) is even better, i can build a lots of units (up to 700+ units) and make allies or declare war against other players, and it has a good graphic (for that time) and nice user-interface.
the campaign is amazing and you can play 4 nations (greek, british, german, and russian) which all 4 of them is nice and has high replay value, you even can switch the difficulty level so that new players will feel friendly while hardcore RTS game will choose hard difficulty level to experience the game better
my conclusion is this game is very entertaining and enjoyable and the price is right too
