I have played War of the Ring quite a few times and I consider it one
of the best 2-player wargames ever made in terms of both gameplay and
theme. I have even spent time painting some of the minis, something I
rarely do. I would have loved to have bought the Collector's Edition
when it came out but financially it wasn't an option.
I have not played Middle Earth Quest and I don't find it particularly
appealing, if I wanted to play a group co-op vs. evil type game I
would probably play Descent.
I'm very excited about where the LOTR LCG can go, both in terms of
lore and gameplay. I really like the solitaire aspect of it as well
though it looks like it will be very quest-dependent.
