Total Annihilation and TA Kingdoms still hold up. They are simple RTS in gameplay and great for beginners in the genre. The graphics are nice and the interface is easy to understand and use. I feel like TA is a true RTS in essence, as it doesn't have the ton of bullshit that other RTSs have, which simply make you waste 2 hours on a single map (I'm looking at you, gentlemen... Warcraft II and StarCraft). Anyway, both are on GOG. TA works without extra tweaks, however, you might want to update TA Kingdoms nGlide to have a stable technical experience, I mean without the boring "AppCrash".
