I think I should preorder 3 since I will want to play the biggest campaign, there isn't really a downside of getting a dlc if I'm sure I'll buy the game, that or wait for sale. Got 1 and 2 in sale when I hardly knew warhammer, so far only paid the blood dlc. Played dwarves, lizards and imric.
-Pirates look kind of cool because of mobile base and "guntreants", no range units sound offputting though.
-I took an interest in tombking lore, pretty sure I'm getting them.
-Chaos looks like ok price but probably not worth it since I'm getting loads of chaos with WH3.
-Twisted and twilight looks cool because I've been meaning to try skaven and moulder is the mutations one right? Also I get to play woodelves without buying the big DLC.
So that would be like 60€ preorder, 10€ tombkings, and 5€ T&T DLC... Even if I only spent like 40 or something up until now it seems excessive and I hate to be supporting such business practices but what are you going to do, TW+Warhammer is an awesome blend... Waiting for sale would mean like maybe 10€ off 60 by end of the year, if I'm lucky enough that 3 should come out several months before winter sales, which is basically the price of a dlc, so I might as well right?! Who knows maybe it's actually a cool race.
Edit: it just seems less stressful to decide the total sum of money I will be spending now, and then just live with what I have (which is plenty, with 3 games and all the FLC that come with them, plus a few gimmicks because I'm and idiot that gets seduced by sales)
