Good point.. but i think some of the nicer homes need some kind of mini games, like some people have listed above, just so your not totaly bored after you beat the game haha look at GTA4 there are only a few( boring, if i may add) things to do after you finish the story line.
I just looked at the trailer again, and the narrator states that " i bought a big house" if the narrator is the protagonist, then we could be looking at a fairly nice home for the begining safehouse. The narrator uses past tense in saying "I bought", so that could be somthing to look forward too!
yeah so is the narrator is the protagonist then i think there should be mini games but i wouldn't really care for them right anyway, i'm more of a play the game to good amount and then fool around with stuff like mini games.
