I've already seen several posts here since the release of 5.0 - but I've yet to see a real discussion about this problem.
Right now, as of 1/11/17 at 8:30 p.m. EST, there are 5 populated servers. Three (3) are Arsenal-only, and two (2) are LTK.
There are many community members (like me) who prefer Deathmatch, CTF, MWGG, and/or other game types over LTK and Arsenal. However, I can't even contemplate how many times I've logged on the last 3-4 months and seen ONLY Arsenal and LTK servers populated.
Of course, there are plenty of servers with Deathmatch and/or mixed game types still active that I could join - and hopefully, after a few minutes, get others to join - but, in reality, the fact that the game has very limited game types regularly available to play is a huge turn-off, especially to new/prospective recruits to the mod. What, if anything, can we do to correct this in future releases? I know that many of the people logging onto the active LTK/Aresenal servers are doing so because, simply, that no other servers are active - and if there was a, for example 6/12 deathmatch server running, they would join it instead of the Arsenal one, but do so because there is simply no other active server.
This is, in my opinion, a critical issue to the future success and sustainability of the mod, but I haven't really seen it discussed much here. Obviously, people are by-and-large going to join the game types that are most popular - however, there is a significant section of the community that I feel is being left out if types like CTF and DM are relegated to "well, there may be a server, sometimes, but probably just LTK and Arsenal."
EDIT: I think one big factor is there are plenty of people playing the mod week-to-week who log on, but get frustrated / disappointed when they see no active DM, TDM, etc. servers running and quickly log off. When there is a DM server active with 4-5 people, it often jumps to 10-15 relatively quickly. My main concern is, over time, DM/TDM/CTF servers will die out if that trend continues, which would be very sad because of how enjoyable those game modes are.
I get that there may quite possibly be nothing that can be done about this - the player base determines what is popular and what isn't - but if there is anything at all that can be done, I think it's a discussion worth having to ensure those players who don't care for LTK and Arsenal do stick around and continue to support GoldenEye: Source.
