I've always been the "newb" or player who enjoyed as much single player action (story-line) as possible. What was good and bad was that some of the story-line in SWTOR (like the last battle vs the Emperor or whomever I honestly forget for the Jedi Knight story-line)... I had to group up with another Jedi Knight (since you can only go to your specific character role's Hangar for your ship), and it was cool you could "share" your ship aka basically give them a lift to whichever planet system. It was just an impossible boss for 1vs1, but 2vs1 we killed the boss in like 30 seconds.
I re-installed yesterday and ran around a bunch on Hoth randomly, besides losing a lot of my binds which made it difficult to battle (so many abilities and attacks I took forever learning and remembering sequences and attack combos.. I've just forgotten). The game still seems great, I did not see as many players on.. but it looks like they did a lot more story missions, I was end-game/max-level when I quit (around the F2P beginning), I also came back as a preferred-player and hacked around a bit, I was paying just so I could play PVP and Raids since they would limit you to like 3 PVP Multi-player games a day and limit you to only be able to do a few things each day/week.
My main character (Jayryan) still has it's PVP set of gear and my Raid set of gear... I haven't had the time to checkout all the new stuff they added, I am thinking about getting back into it for some of the new single-player story missions... I fell in love with SWTOR from the moment my friend's got me playing, I remember dominating Hutt-Ball and a few of the "Domination" PVP matches.. I know they added 1 or 2 new maps (there weren't many), but it was a blast running around in PVP matches or just PVE running around dual-wielding sabers on random planets killing whatever hehe...
I'll never have the time like I did when I was younger, especially my WoW days. I think I was the only one out of my friends to earn "The Explorer" title in WoW as I literally traveled and got an achievement for discovering EVERY area of the WoW map/world lol. I noticed SWTOR added something in which is similar, as I had visited Hoth and immediately started seeing similar achievement telling me I discovered "whatever area", areas I 100% went through years ago lol. I really like what they did with the Galaxy/Star Systems Map(s)... it looks a lot cleaner to find your systems/planets you want to travel to, I am sure they've added some new planets and added content to several as well.
My favorite planet was always Tatooine as it had a special PVP area and a lot of end-game areas to explore. I may hop in a little bit later today just to try and get my key binds down, I tend to enjoy hitting my buffs, then finding my enemies and using Force Leap to start it off, I just need to remember my strategies and combos... hard to explain I guess unless you've played, very much like WoW I suppose.. only Star Wars, so better (more interesting to me anyway).
Diablo III was probably the best investment ever, I think I got it for PC when it came out for $60'sh.. and after so many years it still has replay value, it's free, the game may cost like $30-40 now (not sure)... I was considering buying it for my PS4, but I prefer the PC version. The Seasons in Diablo III are pretty cool, you get rewarded with Set Gear for completing all the achievements for each Chapter. D3 always drops great gear for me and I generally just play single-player Bounty/Adventure Mode... I am hoping to shake the rust off in SWTOR and see if there are any good gear drops, but most were always limited to the higher end-game raids, and generally nothing good ever drops as they want you to spend $$ and buy from vendors, unlike Diablo III which did away with their real $$ Auction House years ago as Blizzard was getting upset that players were literally making lots of $$$ just farming and selling equipment.. heck I knew a kid who was making $300-500 a week selling gear on the D3 Auction House, he was really hurting for income when they shut the AH down
