Only got the game 2 months or so ago myself; only have a decent PC since 6 months and have been busily building up my collection. Brilliant game, particularly like how infantry squads actually behave like squads and how you can make use of cover. You can earn command points (ala Generals) which you can spend on upgrades, with 3 "tech-trees" to choose from. Still looking for the Oposing Fronts expansion, Tales of Valor is said to be a no-no.
Enjoyed the single player campaign
very much, haven't tried my hand at MP yet though. Definatly one of the best titles out there, well worth the money.
