But they do come with some caveats to be aware of:
1) They are an obligation. - They take time. A LOT of time. Someone referred to this as 'a chore' in one Discord server once months ago now. Time that you could be spending engaging with someone in RP more freely. People complain about Powertraders - I was one. When you want to upgrade your base and you're often working alone at it, RP is almost a hassle. Don't let this happen to you - POBs are a group activity, there's where the fun lies and then you realize you can stop and RP once and awhile!
2) They need incredible amounts of material to upgrade or make equipment - see point 1. Lots of time.
3) People get attached to them. Of course they do! They take HUGE amounts of time to build. No one wants to do that every month or year! But I will tell you once I realized that my attachment to my large amount of bases was actually detracting from my enjoyment of the mod - Everything became clear. I do not one bit regret the day I decom'd the network.
4) Bases are a group activity - there's just too much work with the current mechanic to do on your own. They should probably require LESS work, as then if they were destroyed, they wouldn't be so dramatic to rebuild.
5) Once you get to a certain point with base construction - there's not much left to do if you're not running equipment construction except supply the crew and repair needs. And that can get tiresome.
6) Lastly and maybe most horribly: Bases often become a target of OORP rage. Sure, everyone says its in RP. Then they get a pass. But it happens - likely more than I even realize.
When doing events, I typically quote the following right from General Conduct server rules:
The intent of these rules is for everyone to be excellent to one another and to use common sense. Keep fair play in mind and have consideration for others. It's a game, and nothing is gained or lost save for the experience. Credits can be re-earned and ammunition replenished. If you become infuriated, step away. If you make a mistake, apologize.
Unfortunately PoBs seem to have a knack for drama on one side or the other. At some point both sides need to find a middle ground. But in the end, it is a game.
