You can't compare the games in Vegas because I think Bellagio just holds a lot more cachet among the tourists. Mirage games tend to get a lot of people that just bitch about the management of the Bellagio, which means a ton of locals. Besides there are fewer games, you end up playing the same people a lot in the Mirage. I think those factors make a comparison impossible. However I will say that 10-20 is a poor game often just for "looks". Two chips/four chips just never makes the pot look big. One guy I talk to say sometimes he intentionally bets with blues just to make the pot look a little better. Problem is the dealers take the blues out most of the time if you bet them too much. So I think much of it is psychology. The bigger "looking" pots get more action and that explains much of the difference in a nutshell. There are certainly other factors like where the livest players choose to play and what the next level up and down is to determine if you get higher players splashing chips around or tighter players looking to pick up a rack and leave when they aren't comfortable with the limit. One thing though I would suggest never never never doing is voting for a higher limit game. All that does is make bad players play tighter. They know they are long run losers so they play tighter just to make sure they can stay in action as long as they could before.
