I was playing this religiously for over a week, but once I got my Legacy surname at level 30 I completely lost interest, and I haven't logged in for two days.
The storyline did grip me, but it's not enough to contend with the lack of variety. The whole experience just feels hollow. Every quest is a kill quest (with bonus quests to kill more mobs!), and every planet is experiencing a near-identical civil war.
However great Taris seemed because of the continuation of the Rakghoul thread from the original KOTOR, the environments across planets are for the most part ugly and bland. Special mention goes to Nar Shaddaa, for being a tedious, orange-hued corridor run from quest giver to quest giver. By the time I hit this world I was already bored stiff of the side quests, and focused on the storyline quest to get Chewie as quickly as possible (I play a Smuggler).
I have to give special dispensation to Tatooine. As someone mentioned earlier, they nailed this one. It's also the first 'open' planet (or at least, there's a wider expanse in which to manoeuvre) and you reacher speeder riding level around this point, so I'm sure that's part of the novelty. However, this zone felt outstanding in terms of the unique assets and overall atmosphere. It's not just nostalgia speaking either. This *is* Star Wars.
Off to Alderaan afterwards. Major disappointment. BORING stretches of long road and generic snowy alpine countryside. Seemed even longer distances to travel than Tatooine.
And the next planet - Balmorra? - I stepped off the shuttle, took one look at the hideously barren landscape, and used my emergency fleet shuttle pass to go back to the Republic Fleet, from whence I haven't moved except to queue up for a few warzones.
The warzones are fun enough as a Smuggler Scoundrel, but there's only three of them, plus they nerfed the experience in the recent patch. It's as though they don't want us to have fun.
I have burned out badly and it's a complete shock to me. I had every intention of rolling multiple classes, but the thought of killing the same mobs and doing the same horrible quests again puts me off even bothering.
I only play World of Warcraft at the beginning of expansion packs these days, but this horrible mess of a game is making me appreciate the genius of Blizzard. It's a rare game where I can't even be bothered to reach the level cap on one character.
