Chances are you have a suitable set of rules also, so why look at the Kickstarter at all if you are not a newcomer to the genre?
I'm always on the lookout for a good game and this seems to hit quite a few marks. Campaign, semi-random progression, co-op, miniature agnostic,not to mention the rules feel like they fit me better than Rangers of shadowdeep and frostgrave. I'm not a huge on d20 systems.
The miniature range fills some gaps in my collection and add some models I'd not soon get around to buying, but are very nice to have, such as a bunch of animals and villagers. There's always a shinier mini I'd prefer to buy first with my limited funds, but now I can get them all together with some models I very much like in my possession
Yeah, I don't really need any more goblins or trolls, but I do like the overall look. It's nice and classic. A lot of manufacturers are keen on creating their distinct aesthetic, which is great of course, but it sometimes makes it hard to get a good range of more generic looking models. This has the classic fantasy look to me and the rules promise me a great excuse to make that 3d dungeon I've been wanting, plus any type of fantasy scenery I can dream up.
