It's kinda cool how a $5 VPS (Linode Nanode) is able to run a vanilla Minecraft Spigot server for like 6-7 people and still can serve some basic stuff just fine. I get monitoring warnings about >90% CPU usage sometimes, but everything is more or less lagless.

Time to try hosting some other games: CS1.6, Doom Classic, and UT2004 up next.
