               We present <i>GameNGen</i>, the first game engine powered entirely by a neural model
               that enables real-time interaction with a complex environment over long trajectories at high quality.
-              <i>GameNGen</i> can interactively simulate the classic game DOOM at over 20 frames per second on a single
-              TPU.
-              <i>GameNGen</i> simulations do not suffer from accumulated deterioration even after long play sessions,
-              achieving a PSNR of 29.4, comparable to lossy JPEG compression.
-              Human raters are only slightly better than random chance at distinguishing short clips of the game
-              from clips of the simulation.
-              <i>GameNGen</i> is trained in two phases:
-              (1) an RL-agent learns to play the game and the training sessions are recorded, and
-              (2) a diffusion model is trained to produce the next frame, conditioned on the sequence of past frames and
-              actions.
