My biggest problem is that this is easily one of the most repetitive games I've ever played. It needs puzzles, platforming, etc instead of just running from place to place to kill/collect something. Also what's the likelihood of this becoming canon again?
I can agree with that to an extent, but keep in mind this game isn't a puzzle/platformer, it's an RPG. The whole point of RPGs is to level up, obtain better equipment and weapons, and fight progressively stronger opponents. This game does that and far more, in spades.
There are puzzle aspects later in the game on some missions, as you'll see.
And yes, the first fifteen levels or so are repetitive, but it gets far less so as you start being able to traverse the galaxy, visiting different planets, once you get your ship.
Also, considering the huge amount of alternate aspects of the game besides the main story missions, repetitive isn't an accurate description. There's group battles, PvP, group quests, Ops, starfighter battles of three types (PvP 1-on-1, group PvP, and rail shooter missions), daily and weekly events, World Bosses, and the upcoming Guild Starship thing. Not to mention the ability to choose a wide variety of races, classes, and builds for your character, as well as further and extensive abilities to shape the story as you want through different dialogue options (if you want to be a true hero, you can do that; if you want to be a dick, you can do that, too; if you're a Jedi but decide you want to go to the Dark Side, you can do that, and vice versa), you can romance a variety of companions and NPCs, etc. There's a huge amount of fun and interesting stuff to do. So no, simply labeling it as repetitive isn't fair. Nor is expecting platformer gameplay in an MMORPG realistic or apt. You did realize what type of game you were downloading, didn't you?
Plus, I love the main story and side missions. Granted, the "go here/do this" or "collect this" might bore you, but that's also probably because you're rushing through the dialogue and not paying attention to the story and motivation for why you're doing those things. I also wonder why you'd even bother playing a game if you're just going to largely ignore the storyline and not pay much attention to how you're developing your character.
Further, there is a lot of variety in the missions later on. Last night I did a group mission on Tatooine where I had to rescue some humans from a Gamorrean thug and his gang that were throwing them one by one into a Sarlacc Pit. Not only was it a very cool atmosphere to be fighting in next to this gaping maw in the desert, but it was also possible to knock the Gamorreans into the pit using a Force Push.
Point is, the whole point of RPGs is to develop your character and guide the story. Bioware does that better than any other RPG video game company out there, as their Mass Effect and Dragon Age games attest. And that may not be your cup of tea. I can understand that. You may want to stick with platformers instead. This isn't that type of game.
