Archon Studio- Let's build a scifi core set!
This took me a lot longer to clean and prep than I'd expected!
By the time I got through with this, the retail editions have already started to pop up in distribution!
The core set has a lot more tiles and walls to work with, but no scatter terrain and scenery bits. The starter set has a lot less walls and floors, but a slew of decorative pieces to populate your rooms with- take your pick which is more versatile for you.
This stuff is pretty solid once you've got it all cleaned up and prepped.
I feel the Dungeons & Lasers is much more geared toward smaller scale setups- RPGs or small scale skirmishes like Kill Team or any variety of rulesets would work great for these. Obviously it all being indoors probably helps that.
The Rampart stuff is what you want if you're building a ruined town and need lots of cover to block tanks and the like.
