Yoyo,
I don't come alot to say hello but this subject is really something that interest me, as I also feel less and less "entertained" (due to the lack of new map and seeing people quit mainly ) . This game is just a really great experience with a lot of depth and pretty nice community overall.
I also still enjoy watching CJ videos as the quallity have improved alot over the years and even recently, the YWCD is insane imo (Bunny's ep was sick btw).
On the topic, I feel like the "overplayed map" like Race, Galaxy, Descent_v3 are killing the server right now. Don't Get me wrong Race and Galaxy are probably the best maps overall imo (good balance for low and high player / for fun player and speedrunner) and Descent_v3 is one of my Favorite map but i think limiting the time per day or per week for these map could be a start.
Also I was interested on how the movement system works so I've investigate a bit on that thing that define our so loved game and managed to understand and "recreate" a good part of it on UE4 for fun (pretty interrsting indeed). UE4 as a lot to offer for exemple I made it so you can play all with normal fps (Good for lower PCs). Its beautiful, free and easy to learn as there is so many info on internet compared to radiant and I could even add new feature to ehance the gameplay.
To clarify im just experimenting and i will not fully recreate the game myself as its time consuming and im not a game designer (and im a big noob at scripting) . But its an option out there and if that can restore a bit of motivation (for player, movie-maker, Modder, and Map maker) that can be discussed.
Let me know what you think.
