Step 1: Release crummy CoD/CS clone that everyone plays (but better in the sense that it attracts more idiots)
Step 2: Wait for player-base to build.
Step 3: Series of patches over the course of 1-2 years:
3a - Customizable content/HUD, noob friendly drag/drop widget style like android phone
3b - Add cheesy UT movement perks like the new CoD or Titanfall or whatever
3c - Introduce health/armor items in map
3d - Add weapons to map
3e - Upgrade UT movement to strafejumping
.... eventually you will just have Quake again.
Step 4: Watch hundreds of thousands of people unwittingly play Quake.


It's so easy even I could think of it.
