For a variety of reasons, I found myself first at one used bookstore and then another, both of which had wargaming and roleplaying books. I succumbed to temptation and picked up a few items.
Warhammer Ancients and Chariot Wars: I picked up my second copy of WAB for a friend in hopes of perhaps someday doing historical wargaming. Chariot Wars interested me not just because it was dirt-cheap, but also because I have sometimes dreamed of doing a Hyborian-inspired map campaign.
Monster Manual 2: this is the original AD&D MM2, not one of the later ones. It’s a weird collection of monsters, but includes the first appearance of some iconic D&D monsters like the aboleth, tarrasque, and thri-keen. I picked it up because of my current OSG kick, but it’ll probably not see any action any time soon.
Space Marine Codex: this is probably not the latest one, but since the most recent is practically a reprint, and I hardly play 40K, who cares? Again, cheap.
At present, I’m seriously considering a very old RPG, but not D&D–West End Games’ Star Wars RPG. I’ll let you know more if it comes to pass.
