Solo built this browser game. You create a golfer, compete against a persistent AI league, and manage training, equipment, and schedule across a 4 season career. Basically taking Basketball GM's approach and applying it to golf.

Numbers so far: 282 users in the last 10 days, about 9.6% coming back. Had a small spike a few days ago that mostly didn't stick, still trying to figure out why. One good sign though, people who come in through a direct referral stick around about 8 minutes and return at 2x the rate of everyone else. So the core loop seems to work once someone actually sits with it.
