Currently, i'm playing back final fantasy XI on my private server, when i'm tired i switch back to play World of Warcraft : Wrath of Lich King or Legion (also on a private server).
I also play offline mode these games : Grand Theft Auto V, Prey, Agents of Mayhem
I wish I knew how to do this, for my 16th bday many many years ago I asked my Dad for a PlayStation 2 FFXI HDD game combo, I ended up reaching around level 38 as a Galka, forget the class. It was such a difficult game, you really had to know the right people and do something called "lightning leveling" I forget the actual terminology, oh wait I remember, they were called "statics" but I never could figure out how to join one. I have some amazing memories from FFXI though, I spent many hours fishing Moat Carp and selling it on the AH. I really miss that game, FFXIV was a true successor in every way to that game. Thankfully a Realm Reborn fixed everything and made it perfect.
Still it would be awesome to have your very own private server to tinker around with and just do like insanely quick leveling solo and wander around and see all the stuff. Can you even modify your speed like your mount speed?
on-topic: I am currently playing nothing, just waiting for God of War to release, should be a blast. I have been watching Koko the Gorilla videos lately... the one with Robin Williams playing tickle with Koko is probably the most genuine happiness I have ever seen in another human being. Makes you wonder if we got this whole thing called life wrong. Maybe instead of endless greed and envy we were supposed to create a symbiosis with the nature around us? As Aristotle said, we are different than the animals and that different part is what we should focus on, but what if that different part was meant to make us avoid are animal instincts (greed/envy/lust) and instead create a symbiosis with the world around us, instead of hitting that world with a sledgehammer to make it the way we want it over and over and over... maybe all of us could laugh with Koko like Robin did, or any variety of unimaginable things we failed to accomplish with treating nature as an object instead of as a source of Light of Consciousness.
on-topic, video is on topic, cause its tickle games Robin Williams is playing
