I played at the tail-end of beta, and even then I didn't have a lot of technical difficulties getting into the game.
However I didn't buy the game and am not playing it now simply because I didn't like it. Whilst the voice acting and storyline holds a lot of potential, the game is horribly lacking in three key areas for me.
First is character customization. Visually, you are stuck with a handful of presets for your characters appearance, and it's not very long before you run into a dozen clones that look and sound exactly like your character. It's very immersion-breaking seeing your twin standing next to you in a cutscene and you're wondering, "Was that my character that just said something, or this guy next to me?"
Leveling is very formulaic and linear, almost perfectly mirroring the the WoW model. The only deviation is that you don't choose your *true* character profession until level 10. Compared to other MMO's I've played, there's very little flexibility in how you build or customize your character's abilities. Every time you gain a level, you're given no choice on what abilities you get to buy next - most of which are just upgrades to old abilities. The only *choice* you get is you eventually get skill points where you can gain some small specialization with certain abilities, like a 2% increase in healing.
Finally, there's way too many gameplay mechanics that break immersion too much and too frequently for my tastes. I already knew Lightsabers and Blasters would be far less powerful than they are in the movies - even I can understand that there's no easy way to make them feel accurate. Unfortunately there's so much more than just that. There's the aforementioned need to "buy" all of your character skills when you level-up. While this is an established MMO mechanic dating back to EverQuest, it feels completely out-of-place in this game. My other big gripe were the boss fights. Even at low levels you will fight bosses that break the game rules in order to make them challenging to the players. The worst one that stuck-out in my mind were the Level 10 bosses with special "Boss Level" immunities that automatically make then 100% immune to anything other than direct damage and *maybe* some debuffs (where are very limited at that low of level). If it were high-level and/or endgame content, I would be more accepting of this kind of in-game cheating, but not when I'm barely out of the training planet and on my first Flashpoint.
