You know, you don't have to rent a server. You can rent a cloud server using Amazon Web Services. These are basically virtual machines that allows you to host your web server or game servers.
There a pretty good guide to get you started right here: https://steamcommunity.com/sharedfiles/filedetails/?id=940000002
Take note that if your planning to run that server 24/7, it would cost you at least $53 USD per month. Make sure you got the money in your pocket before getting started.
Regarding the microtransaction discussion, will there be plans to have "Paid DLC"?
The paid dlc would work like this. We get unique cosmetic that can get you the higher quality items that can only be unlocked via a purchase or it can get you instance access to that item without trying to grind through the game. It should be roughly cost me around $5 to $8 USD, it would be a great alternative way to support NWI directory instead of using the microtransaction in place.
As long as they don't put in Loot Boxes, Pay to Win crap, and all the repetitive progression system, I'm cool with that idea.
I was really hesitant to give this game another go. Due to the bad FPS and awful net coding. I'll give it a pass and wait until the dev improve the optimization of the game game and the server. Oh well, it time for me to go back to playing something else.
My spec in case anyone wondering:
GTX 1060 (6GB)
8 GB RAM
