Ah, Red Alert 2. I really loved that game, haven't played in forever. It was before I had ubiquitous broadband so I never really played it online - does anyone know if it is still possible to do so / whether anyone does? I'm sure I'd lose within minutes against anyone still playing today, but a 4 way multiplayer battle would be amazing.
EDIT: figured I could be less lazy and find out myself. It appears you can play online through https://cncnet.org/red-alert-2. Now all I need to do is figure out where to buy it and how to make it work on my Mac. I suppose it's old enough I might be able to play via a virtual machine.
Definitely check out OpenRA, a modern open source and cross-platform reimplementation of the old Westwood engines, with support for CnC, Red Alert and Dune2000. There's a few changes to add a bit of balance but its still got the classic feel and there's an active multiplayer community online with regular tournaments and everything.
