I ran into a 'Meh' period probably between 2 and 3 years into Eve - just logging in occasionally to chat, stuff like that.
I'm not very good at 'meh' playing. I'd like either to pursue something with passion, or not put much time into it.
I still do like the game, and mechanically its gotten better, but because the goals I love to achieve aren't achievable in the time I'm willing to spend on EVE.
Most aspects of gameplay felt better the first few times than when I've done them a thousand times over. Moreso for PvE activities and less so for interacting with other players. I used to love posting my killsmails on corp forum and discussing particular fights, but after a couple of hundred kills, it loses its luster.
My personal Golden Age was 0-3 years into the game. When most gameplay was still fresh and involved learning new stuff. Now I'm much better at predicting outcomes of things I do (both mechanically, but also RP-wise), which sadly tends to make it less interesting and reduces my actual sense of choice and freedom. It sometimes difficult to explain to bright-eyed new players why you sometimes don't undock with those high-sec war deccers around. I mean, they have a much smaller ship, and are sitting there on the undock ripe for the shooting! Why aren't the more experienced players undocking to make use of this golden opportunity? ....
I'm also better a predicting the amount of effort and time it takes to get fun things off the ground within a diverse community of on-and-off volunteers like EVE is and that it takes *a lot* of time and effort to be a content-creator instead of mostly a content-consumer.
I also believe that to use EVE as a glorified chat channel can actually be detrimental to the gameplay of others. You create an illusion of people being there, but they tend to be people not willing to put much time and effort into cooperative gameplay (although maybe sometimes their characters say the would). Lot of people in chat channels, corps, alliances or other EVE venues seem to be lurking and waiting for someone else to come along and entertain them. Someone else to create content for them. Reactive play as it were. I prefer not to play that way.
Basically, what do you want to get out of EVE? What are the goals that excite you as a player, and can they be reasonably met with the tools you have on hand? If you don't have goals, or little hope of achieving the goals with the tools you have, then you might as well not play.
