Converting POIs has also become my fav thing to do, rly dig the challenge of it, and it looks like it fits in, like is part of game/world. Things made from scratch often look/feel exactly like that, never quite feel like they fit in, even though I also like the challenge of it, and have made/seen some really nice designs.
A few friends and me took over the Outpost 7 mil base in the forest biome in Pregen 1. Thought it would be too much to defend at first, but now we're on day 18 and things couldn't be better. Just installed automatic doors at entrance and garage where we keep all our vehicles. We also lucked out big time and have a mine below with almost every ore in it. I maintain the vault in HQ basement as a community supply/crafting area, and up top everyone has their own building. Only a few of us are ever on at once, but this place ended working out great. Even has built in farming plots our designated chef is using, though now she's installed a ton of her own too.
Aldo's, ahem "FREEE BRAAINS" is just up the street. Got it powered up with blade traps and turrets now. We used the firehouse for first 3 BMs, there's not much left of it, lol. We're about to give this new spot a good test on the next BM, excited for it, we are far more ready this time. Just hope the night doesn't start out with half a dozen Demolishers, again. This is why I put all my turrets on switches now, last time was a huge learning experience.
