I'd like to see 2 additional groups added to the game.
1) With properties like the ranch, why aren't their farm animals or the ability to grow pot. A perk to a ranch could be that if you grow pot, you have zero addiction to it. Also, with a PI you can own a sailboat. Why can't we sail to like the UK, or Hawaii?
2) I'd like to see more activities in foreign countries. Like in Japan, you could attend a Sumo wrestling match. The UK you could visit Scotland, or London bridge. In Hawaii, you could throw someone in a volcano after mugging.
