Wildsea is great, the setting is wonderful and I'm really enjoying the mechanics so far. We're 4 sessions in and have played through the introductory adventure. It's a very solar punk hopeful setting (at least how I'm running it) which we all need more of at the minute I think.
I'm looking forward to getting the books for slugblaster, I've had a read of the PDF and it sounds like a lot of fun.
Is there anything you're particularly interested in from the bundle?
For car camping a double roll mat and double sleeping bag has made a world of difference especially for my wife who's a cold sleeper, sharing a bag let's her steal my warmth. We've had a Vango comfort roll mat for a good few years now and it doesn't pack small but it's nearly as comfy as my mattress at home.
