StarCraft II: Wings of Liberty

Age of Empires taught me to study build orders for a small edge. StarCraft II takes that habit and removes your thinking time. Worker count, supply, scouting, expansion timing: every second you waste shows up in the next fight, and the Bronze-to-Grandmaster ladder is unforgiving about it. I never pretended I would climb it. The three campaigns are the easier way in, and Wings of Liberty is free to start with. Blizzard has wound down major development, though the game is live and plays as sharply as ever. Expect to lose a lot online before the pace starts to make sense.

StarCraft II still hosts a dedicated 1v1 ladder and remains the benchmark for competitive RTS design—the Grand Masters scene is genuinely worth watching. But it's CPU-bound in a way that hurts on low-end machines. Late-game army micro drops to 30–40 FPS regularly on entry-level processors, and the 30GB install is the largest on this list by a significant margin. AoE2:DE handles the same 1v1 competitive niche better on constrained hardware, which is why SC2 sits last. For players who specifically want StarCraft and have a slightly better processor, Wings of Liberty's campaign and the ladder are still worth the install. For everyone else, AoE2 is the clearer call.
