1. Single-Player Story Priority
Focusing initially on the single-player campaign ensures players absorb the scale of Vice City and Leonida before jumping into competitive multiplayer lobbies.
2. Server Infrastructure Stress Testing
Postponing multiplayer activation by a few weeks prevents Day 1 server overload, ensuring smooth character creation and property purchasing when GTA Online goes live.
3. Economy & Business Balance
Staggering multiplayer launch allows Rockstar to fine-tune in-game business payout rates, heist payouts, and anti-cheat protections.
