I'm rather enjoying SWTOR. I'm slowly making my way up. My Imperial Agent (Sniper) is level 27, and has been a lot of fun.
This blog is probably going to have a lot of SWTOR posts in the near future, mostly because it's the new hotness and because--for all that it is a WoW clone--there are some very interesting differences between the two games.
Normally, I don't roleplay at all in MMOs. In fact, I've gone on record as saying that roleplaying is irrelevant to MMOs. But I find myself assigning personalities to the characters I make in SWTOR, and using that to determine which choices I make in conversations. I'm usually Light-side, but it's interesting how much variation there can be.
Imperial Agent - pure Light-side for the greater good of the Empire. Absolutely loyal to the Empire, but feels that Light-side choices brings order to the Empire, as opposed to the chaos of the Sith. This works astonishingly well with the Imperial Agent storyline so far.
Sith Inquisitor - mostly Light-side. Is snarky and insulting towards the pompous, arrogant Sith, but respectful to those Sith worthy of respect and to the lower orders of the Empire.
Republic Trooper - again, mostly Light-side, but will go Dark Side to foil the Republic's enemies, both foreign and domestic.
Jedi Knight - la belle dame sans merci. Again, Light-side for most choices, but does not show mercy to defeated enemies, and kills them instead. Follows the principle that Batman should have killed the Joker, rather than imprisoning him in Arkham Asylum, as the Joker will inevitably escape and kill more innocents.
It's actually kind of surprising how many Dark-side points the last will get you. I'm running about 2-to-1 Light-side to Dark-side points.
