I believe there is lan options for both 1 and 2? If so you can also try a VPN for online play.
EA's license for LOTR games expired so they can no longer be involved in LOTR games (old games are not even sold through Origin for example). Warner Bros has the current license but they have no history of RTS games. Could try the mod for Total War.
It's sad, the servers are shut down and they no longer print copies of the game so the price has inflated to over $100. Luckily I managed to grab my copy of BFME2 and ROTWK before that happened. LAN works over hamachi and stuff but it's pretty difficult due to the version mismatch and anti-crack features.
