I am finding ESO to be more like GW2 than like skyrim.
I have played ESO for 1 month and I have been playing GW2 for only 2 weeks so bear with me. In GW2, there just seems to be more stuff going on everywhere. Prizes and awards and bonuses everywhere.
ESO less of that.
I fond both to have some stunning graphical scenery. I find both to be slow in the walking dept. In ESO, you can buy a horse for 17,000 gold. I played for a month and I have banked about 5K so far.
The 4 player dungeon raids were quite challenging and fun.
I haven't figured out the GW2 skill system yet, but I liked Elder Scrolls skill system better.
For PvP, I have only tried Gw2 keg game and I thought it was a hoot and fun. In ESO, I wandered to the PvP area and it was quite exciting to see a 30 versus 30 battle going on trying to control a particular land mark. It was an epic battle where I could wade in and help out, healing. I was really impressed.
Leveling seems on par with one another. Guilds seem decent in both cases too.
Glitch wise, they seem even to me also.
