I quite like The Lord of the Rings Online. I have 2 level 50+ characters, they’ve reached Moria, which opens up another stage of the game, and Turbine are continuing to add to the game with a new expansion coming this year to raise the level cap even higher.
One of our group proposed forming a kinship, and we have a couple of new to LotRO players joining us, so a couple of us have been working on some low level characters so we can start a lvl 20+ group as an almost full fellowship. Should be interesting.
Depending upon which region packs you’ve bought you have multiple options of how to progress through the levels, so you don’t necessarily have to go through the same missions/stories with new characters, apart from the epics (that form the fundamental story missions).
Lord of the Rings Online has been a good time investment for me, and a lot of fun.
