Instant FPS

Instant FPS action — click play, type a name, you're shooting in 30 seconds. Counter-Strike 1.6 on PlayCSOnline streams the engine on demand: by the time you choose a server, the engine module is already loading.
▶ Play Instant FPS Now30 Seconds From Click to Spawn
Time it yourself. Open the homepage, type a player name, click any server in the live list, hit Join. The engine module (≈40 MB) downloads in parallel with the map (≈3-8 MB depending on the map). On a 50 Mbps connection that's about 6 seconds. Add 5 seconds for engine boot, 4 seconds for connect handshake, and you're aiming down sights at the 30-second mark.
Compare that to Steam: install client → download CS 1.6 → wait for first launch → wait for VAC update → finally connect. Hours, not seconds.
