This free one-player game allows you to play as an NBA general manager, attempting to assemble the perfect roster through drafts, trades and free agency.
You can start as the manager of any team in any season in history. Once the game begins, all the other teams are run by AI. After the first couple of years, nobody will (except by chance) get drafted by the same team they did in real life, so it quickly becomes a sort of parallel NBA universe which can be fun to follow regardless of how your own team is doing. You can, if you want, continue playing centuries into the future with computer-generated players.
Players come into the league in the same year and with the same general skills and potential as they did in real life, and then develop randomly based on their potential. In general, the stars in any given playthrough are the same as in real life, but there will be many real-life stars who are busts and vice versa.
The game outcomes, of course, are random, weighted according to relative team quality. You can zip through the entire regular season and playoffs with two clicks, or you can read the play-by-play tick slowly by for each game, depending on your mood.
I find it’s entertaining for many levels of focus; you can play it with half your attention on something else, or you can get intensely locked in for hours. There’s even an auto-play option, so you could just watch an alternate league history play out and not have to do anything at all!
And it’s free with no ads, just done by some guy as a public service and constantly being updated with new bells and whistles. All the game data is stored in your browser cache, though, which means that you can’t play the same league across devices.
He also has NFL and NHL versions, which I haven’t tried.
