Age of Empires, Command & Conquer

[George]

Ahoy,

Back in the day, a friend of mine introduced me to Age of Empires, along with Command & Conquer Red Alert. Both great fun, haven't played them for years though. 

Anyone still play either of these? Or...are there better alternatives (multiplayer would be nice) that I should look at?

Thanks
