I used to play mods when I was rather young. Problem was, I didn't know what an IE was for Red Alert 2/Yuri's Revenge. After a few years of not playing mods (because I didn't know what a virus was until it was too late), I decided to go look for something to actually spice up the gameplay and well...I found a few. ModDB is the best place to acquire a mod that interests you, considering the fact that they actually give a shit about checking to see if files are infected or not.
Current mods I have:
Mental Omega 3.0 (currently uninstalled to make sure no issues occur with Mental Omega 2.0),
Rise of the Reds (Generals: Zero Hour mod),
Shockwave Mod (Generals: Zero Hour mod),
->Star Wars: Republic at War (Star Wars: Empire at War Forces of Corruption mod),
Tiberium Essence (Tiberium Wars mod),
Twisted Insurrection (Tiberian Sun/Firestorm Mod[?])
