TL;DR
Add more options to the "search filters" tab in the "browse public games" menu.Story (feel free to skip this)
Picture this situation: You join a public multiplayer game (after finishing Gelba in your single-player save so you are tired of space age) only to be met with space age game after space age game (or you don't have space age and want to filter these servers out). After finding a server without space age (finally), it has a ups of 15 and because of this, you decide to do something I legally cannot say. Once you have finished your grand escape from the FBI, you try again. This time you found a server with a ups above 45 and it isn't running space age (after a few hours). It takes a full minute to connect, but you don't think anything of it. Upon typing "hi" in the chat, your message does not appear. 3 seconds later, your message has appeared. The ups is 60 the game seems to be running fine, however upon asking the server owner how good their wi-fi is... they reply by talking about how amazing their mobile hotspot wi-fi is (it sucks). One quick trip to your therapist later (and an extended session), you try again at finding an at least uncommon quality multiplayer game. After 4 days straight (no sleep no eating no bathroom breaks) of searching for a good game, you find one that meets all your previous criteria for a good game, but nobody there speaks your language. 1 day later and people are beginning to make reservations to attend your funeral.What?
I suggest 6 new filters for the "search filters" tab in the "browse public games" menu.1. Space Age
2. Ups (Max) (includes box to type in (numbers only))
3. Ping (Max) (includes box to type in (numbers only))
4. Region (99% sure people are going to get mad at me for including this, but I'm going to mention this anyway

5. Host Uses Your Language (if the host's game language = what your game language is set to) (could also be a drop down menu)
6. Achievements (not in image cause this was a late thought and I don't have time to update the image for it) (more a no /editor check than anything else)
