That comic is from some lame EA LotR game, you can swim in LotR Online.
There are actually a few LotR Online folks here, including a developer or two. First off, it is an MMO, so if you've hated every MMO you've ever played, this probably won't convert you. However, it is a very well polished MMO, and it does a fantastic job recreating Middle Earth and involving you in an epic storyline. The quests are the real draw for me, they are layered and interesting. The book quests really made me feel involved, like I am taking part in something much larger.
The classes are all solid, most of the melee classes have some type of combo system that I find rewarding and isn't just mindless button mashing. It's also quite beautiful, traveling through Moria and the huge stone hallways, or wandering around the shire, there are quite a few visual treats.
