Mods.
I played 800 hours without mods. Then switched and did another 4,000
For most people, I would say you only realistically get a few hundred hours out of CE. Unless you like building in which case you might be able to double your time with the game.
For many people, they keep playing simply because they feel they are quitting if they don’t. If they don’t relogin to refresh their buildings/thralls, then its like they wasted their time. The problem with this mentality is they’ve finished the game long ago and the time played wasn’t wasted as they had enjoyment. But they’re wasting their time now.
If the game is done for you. Move on. Seriously. There’s nothing wrong with this. Most of you have literally hundreds if not thousands of hours. For a $30 game that’s amazing. Most $60 titles give you 8-10 hours nowadays.
If you are on PC, mods can rejuvenate the game. But I highly recommend playing on someone else’s server to see how the mods work with each other before doing your own. When you do your own, start small. This isn’t Skyrim.
Also if you’re truly not ready to give up the game. Don’t be afraid of taking breaks. And yes that means letting those structures and thralls you have lapsing. I have personally gotten 1-60 (and more due to mods) several dozen times, and at least half of that is on 1x exp. Starting over is not bad.
Starting over gets way easier the more you do it. You start learning what you need and with the new stations, starting over is easier than ever since you don’t require T2 and T4 thralls to make basic progress not drag on (1:1 ratio iron/steel to reinforcement, steelfire, and alchemical base is a must as many of you know when building larger structures and bases).
And once you get used to starting over, you can learn to enjoy some of the more seasonal based servers which change up their themes occasionally which helps keep things fresh.
If you’re of the role-playing personality, then RP servers will keep you entertained for potentially years. Much better and higher quality RP in Conan than in WoW, or EQ, or SWTOR, or any other MMORPG.
