I’ve been playing Kingdom of Loathing for about a week now, per Rob West’s recommendation. KoL is the kind of game that I get addicted to very quickly: it’s turn-based (so I can’t just keep playing until I win), it’s got some jokes, and there are quantifiable goals that are not easy but that are definitely possible without too much thinking.
With these kinds of games I try to figure out what the ideal strategy is. When I’ve proven to myself that I’ve figured out the ideal strategy, then I usually (hopefully) stop playing.
