These days I’m really into Vassal. I think it’s great. It means I can leave even quite large games “set up” for days on end while me and other people in the same boat (young kids and a full time job) can play a turn here or there.
This has meant that I can revisit games with fairly complex rules, because I get to work through them at an enjoyably leisurely pace. Lately I’ve had a couple of great games of Red Storm (latest in the ‘Downtown’ series), and it’s pretty complex but using a computer to provide the playing space is a Godsend, as I can squeeze in my move after the kids have gone to bed.
Vassal has basically saved my gaming hobby.
