and how much fun would casual play be for someone who never touched the game?
Well stories are all fun and unique to each class. All voice acted and good shit. Combat is good mmo type tab target shit. Once you get a companion it becomes sorta trivial on normal story mode but if you want it difficult, just send your companion away. You can also change the roles of the companions from tank, dps and heals. They do have other harder modes I just cant figure out how to switch. The quest system is sort of like wow type but you have your main class story quests, then the main planet quests plus a slew of side quest stuff from hub to hub.
Dungeons are also like WOW now with dungeon finder, you can queue up from anywhere, it auto teleports you to them and levels you up to lv75. They are really fun SW type shit with jedi, sith, robots, and SW music and shit. They drop really good purps for your level.
There is also PvP instances, which also levels you up to 75. But I have not fucked with PvP that much.
There is also space missions too and a dog fighting thing but, again, I hanve not fucked with that either.
So far it seems pretty casual friendly I got a mercenary from 1-50 in a few casual days outfitted in full dungeon purps. Although I still need to backtrack and do all the planet and story stuff still.
They made the most tedious part of the game great which was traveling around. You get a speed boost, all quick travel points on a planet are open, and you get a 6 min hearth to any quest hub on the map.
End game and all that other shit I have no clue about.
If you do decide to play I reccomend to sub for a month $15 and it opens up a ton of shit for you permanently plus you get some cartel coins to spend in shop.
