I love the Forge World models, I think some of them are among the best I own. But, I think it would be difficult to recommend someone starting up with them now, without mentioning the following: an awful lot of Warhammer Forge stuff is disappearing from sale, not least of which includes the Monstrous Arcanum book (gone!) and more relevantly to Chaos Dwarfs, possibly also the Tamurkhan book (still available but price slashed, as though they’d trying to clear it).
Then there’s the models: Tamurkhan (gone!), Land Ship (gone!), Armoured Handgunner Command (gone!) and so on. I’ve not kept track too closely so I’m not sure if any CD stuff has gone off sale yet, but it seems like only a matter of time.
Add to that persistent rumours (which you may decide not to believe, of course) that the End Times that GW are currently running is a build-up to change everything in 9th Edition next year; with many special characters already dead, and CDs not even getting a mention, except that the entire Ogre nation is marching West (straight through where the CDs live)…?
So there’s a major question mark hanging over the future of the range. If you can afford to get everything you want in one go there’s no problem, but if you’re planning on picking up character A here, unit B there, unit C the next month and character D the month after that… consider that at any time, any of A, B, C or D might be removed from sale without warning. You might also consider asking yourself what happens if 9th Ed really does change everything. Will your gaming group be OK with you using an 8th Ed army in 9th Ed, or using house rules or community rules? Or is your gaming group the kind that only likes to play “official” rules and wouldn’t let you use your CDs if they didn’t have a current army list?
The WF CD models are fantastic and I endorse them heartily. But they’re also expensive, and before buying you should be sure that you won’t regret your purchases if the worst happens (models go off sale so you can’t complete your army, CDs don’t get “official” rules in 9th Ed, etc).
