I have a question that kinda needs answering but I am unable to answer it myself at the moment.
Can a Raspberry pi run the UE4 Dedicated Server?
Edit 1: Alright bit of an Update on this - Asked in the UE Slackers Discord Channel.
In theory a Pi should be able to run a UE4 dedicated server. The person that I talked to said that their dedicated server uses 179 meg of ram with no players and 1.4% of CPU.
