Which games do you think have the best pacing?
For me to name a few:
Resident Evil 4 - This is the king when it comes to pacing in games and the reason why it's my favorite of all time. Never a dull moment and the game switches between battle, puzzle and bosses with great finesse. Environment and enemy changes are done to great effect as well.
Uncharted 2 - Besides the stealth levels in the beginning, I feel like the rest of the game is nearly a perfect ride with barely any moment overstaying its welcome.
Super Mario Odyssey - Not having to restart a level from the beginning after getting a moon really keeps the flow going.
