Well I was thinking of playing but realised I didn't really have enough natural terrain so I started thinking about what to add and decided some rocks / rocky hills would be a good bet, they are generic enough to work for sci-fi & fantasy but also offer lots of options for movement & LoS blocking.
I had a look on tinternet for some inspiration and started thinking about maybe going with something kinda modular so at least one hill that can take a rock pile or maybe a house...hmm...
Then I started thinking about my sci-fi buildings, unfortunately Micro Art have stopped making them and now I look at them they are a bit too Star Warsy so my mind wandered some more. I definitely wanted a rocky hill that'd take a sci-fi house so before I start on the rocks I need to plan some new house. A few cards models and tinternet searches later and I stumbled on these in The Works...
As you can see I removed the lid from one and flipped it; you can also see a Hex pencil pot I picked up from Hobbycraft and some bits from the Maelstroms Edge Terrain sprue 1.
I think these will work well. I initially just got the one but ended up going back for more...
My head fluff for these is they are a kit house, cheap(ish) and cheerful and can be used to make a simple homestead or a small settlement. An advantage of them being the same size and shape is they can be combined into different combos...
I'm not sure at the moment how modular I want to keep them so will think on it and sketch out some ideas. I've ordered some more terrain sprues and will be putting an order in with Oshiro for some gubbins too.
Now I know what I'm doing with the sci fi buildings I can go back to thinking about the rocks and sketch some ideas.
