I just bought a new netbook (Asus 1005PR) and would love to be able to load a Civ type strategy game onto it. The problem I'm running into is that the older games that it can play (Civ II, AoE II...) all require DOS and won't run in Win 7. I could probably install DOSBox to get them to work but I'd prefer another solution. Does anyone know of a Civ/AoE type game that can run in Win 7 but also have low enough requirements to work on a new netbook? Thanks.
