Command & Conquer 3: Tiberium Wars

A wholehearted "worth a buy" and one of the best in the series, this retro pick still plays brilliantly today with no mods or patches needed. The GDI and Nod campaigns, sharp AI that flanks and probes intelligently, deep unit variety with upgrades, and cheesy-but-captivating live-action cutscenes (Kane especially) all hold up superbly, and even the juicy green tiberium crystals are a delight. A great-value, highly playable classic.
