Is Star Wars The Old Republic really a single player MMORPG
You can play completely single while SWTOR leveling. All of the group quests tend to be designated this kind of and there are sufficient single missions to where you never need to do the actual team missions if you don't want to. A few of the group quests are even soloable for those classes and pretty much every Brave 2+ quest can be finished after you have a few levels across the quest if you actually want to get it done.
I am not sure at this time how much game play there is while attempting to single once you have capped your own character however.
Additionally, you don't generate any sociable points with out grouping which can be accustomed to purchase gear, but the social gear I've seen tends to be mainly a aesthetic difference in comparison with gear had in different ways. Group content additionally has a tendency to possess much better end rewards, however so far if you have the appropriate crafting SWTOR skill you can make similar SWTOR items and you will make use of commendations to buy better gear.
