I used to love almost everything about Warhammer/40k when I was little – collecting the figures, painting, reading the rulebooks and all the extra blurb – except actually playing the games. Which are terrible.
Some people enjoy rolling endless dice and consulting tables and charts but there are so many better wargames out there now, which are much simpler/more fun/more strategic/etc. Games Workshop games have always been like an introduction course for bookkeeping! Which is a shame, because the figures are great – especially Island of Blood, they look awesome.
Basically if you like collecting/modelling/painting/spending huge amounts of money then fair enough, if you want to play a decent board/war game then definitely look somewhere else.
If it’s just a way of getting into her knickers though, game on!
