You know, I actually looked up the RPG mod Q suggested and I would love to see GTA Online take this type of spin:
Basically PvP zones and stuff because the world they've created is way too beautiful and immersive to be wasted on an open-world deathmatch. I think the ability to also choose classes or have occupations (if you so desire) would be neat as well: stuff like a bounty hunter where if you're only that class you can claim player bounties, or cops, medics, etc.
The game in its current form is an absolute fuckfest: it is literally people on flying motorcycles destroying people's cargo (that they worked hard for) in a matter of minutes... it's hilarious and cruel in both ways. My favorite aspect of the game used to be hunting player bounties but it's all too easy with the homing missiles on the MK2.
I'm really desiring an amazing open world online experience and GTA Online just isn't it fam. I thought I could get into Phantasy Star Online but despite being free it just isn't my cup of tea at all. I have reverted back to emulators of the now defunct Star Wars Galaxies: an MMO that was and still is ahead of its time. I've also been reminiscing over PlayStation Home as well.
