I've been playing the ESO beta this weekend.
I'm quite enjoying it, but it lacks a few things that I've come to appreciate in MMOs.
The main thing just being how many players there are around you at all times.
Some people might like that, but I find it really annoying when there's fifteen people all on the same quest all gathering around chatting to the same NPC or trying to do the same thing.
I much prefer the style of say, Star Wars The Old Republic, where quest areas get locked off to individuals/groups, so once you enter, only yourself and your group are with you and you aren't plagued by other people getting in the way.
I don't think I'd mind it too much if at the very least it wasn't possible for every player around to fight the same enemy as you currently are. Takes away the challenge and interesting battle you and a group can have, if everyone is just shooting at it.
And because of that, respawn rates are crazily high. Kill an enemy, stop to check your inventory, turn around, and the enemy is back again.
I'm quite offput by paying for the game as a whole and then paying on top of that as a subscription.
I feel kind of cheated to buy a product and then have to pay more constantly to continue playing.
I much prefer the one-time payment or (possibly controversially) the F2P with Optional Subscription model.
Or even just a subscription without a large initial purchase.
But, I am enjoying the game so far and I have some money saved up from my job and also money from Christmas, so I might just buy it when it releases.
