This is less of a 'game' request and more of a 'Minecraft server' request which I hope is fine considering that some of the top-end MC servers are separate games in their own right...
Though if you know of a standalone game that fits these criteria as well, then let me know.
(worst case scenario I'll ask in the Minecraft thread I guess.)
I want some kind of minimalist PvP/CTF "You have X minutes to gather resources, craft stuff and build a base w/ defenses around your objective then go and assault your enemy and capture/defeat their objective while protecting your own objective." server that doesn't throw a bunch of 'purchasable perks/different classes/cosmetics' P2W/pay2havefun BS in my face and overload me with info. Just pure vanilla experience, where everyone starts equal.
Something along the lines of The Walls map, or games-wise, the original Ace of Spades (now Build and Shoot, but that has gone to hell...). I tried Blockstorm (which while neat doesn't really have much focus on the building/crafting side of things) and briefly wanted to check out the Hypixel server but again, the extra layer of "an odd interface that uses inventory items to show your profile and stuff coupled with the classes+perks+other bonuses" was just blegh to me.
I also tried out a Minetest server that did exactly that, but Minetest...Well, it's not fit for PvP of that kind. Not to mention that some of the people on the server were immature at best.
