Scatty I have weird connections in my head, so sorry for that. Of course, this games are different in terms of "global" gameplay, but in most taken moments you do the same things: wave your sword (aim your bow/cast your spells - no matter) trying to kill this annoying enemy. Both games are realtime, both are stats-dependant, both are first person and both have requirements of two skills: quite fast reflexes and ability to orienting in 3D-world. So they are "similar" for me.
Also, that makes me quite wary, as I am not a big specialist of it.
On the other hand, I have more skills than I thought (as I was able to play Borderlands recently), so actually it have sense for me now to try this sort of games too.
