I tried playing it once years ago, when it was still buy only but had a brief free weekend. I didn't last more than an hour though.
Soon enough I was fighting a deer in the woods who posed no threat to me, and I just stood there using the 2 or 3 skills I had, and waiting for them to come off cooldown to use them again. It felt pretty rote and mindless.
The reason I made an exception with XCX is that I think it did cross the line into something more involved. Positioning was a constant concern to trigger the added effects on your skills, as well as the order in which you performed them to trigger combos, and trigger your AI teammates' abilities, without which you're gonna get your ass kicked.
I know the assessment of a newbie who's only made it to level 3 or so is bound to be lacking, but my point is that my first impression was that the gameplay was no different from the one that kept me away from playing MMORPGs in the past. I'd be happy to be mistaken here, but it's an uphill battle to undo a first impression.
EDIT: I might give
Warframe a try. It's more action oriented, and it is multiplayer. From what I know it is lacking on the huge world and interesting lore department, things I was really hoping to immerse myself into.
Does anyone have some opinions to share on it?
