There should be an option for either starting experience pool or increased experience generation. It’s not fun to start out a game knowing you can’t level up anything at least for a while.
If you don’t want to wait you can do just that, Wait. ^ Will open the wait list and then just pick how long you want.
Combined with setting your start time you can get set for your first loot run right from the start.
Ex. Start time 6pm and wait 1 hour - 1.5 hours depending on how long it’ll take you getting to town. Arive at nightfall and loot all night long.
Now the problem with ^wait is that you will become hungry much quicker, and because it’s hard to visit towns during static spawning, food and water is much scarcer.
I suppose this work around works if you only want small amounts of XP, enough to level your firearm ~1 level.
