How about play a LOTR game instead instead of trying to find similarities in a totally different game.
Or use your own creativity to do what you're trying to accomplish.
There are no LOTR games worth playing these days... Honestly there needs to be a big dev team that needs to get LOTR rights for a game. I wanna see Rockstar do a LOTR sandbox game. That would be awesome.
"theres several lotr games. play those. no offence intended. im just saying"
Most are crap, especially the ones by EA. Of the adventure games Aragorn's Quest and The Hobbit are the only ones really worth it, that I have played in any case. The Fellowship of the Ring by Sierra is good, but you'll only get a third of the story. Haven't played War in the North, though.
