Do I enjoy the game as much as I did back then? Yes, but in a different way.
I don't remember the detail of how I found out about AQW, I think it might have been an ad somewhere, I had played AQ and DF before (although not to any decent level, I just created a free account and messed around, I also remember never getting past lvl 55-ish in AQ, it was just so slow paced and I never had the patience for that, even today, it's still feels soooo....sloooooow to play), so i knew about AE beforehand.
Back then, I enjoyed the game for it's simplicity, it was easy to get in to (pick class, click buttons, kill monsters, can't get more simple than that), it was always fun to just run around and kill stuff, gain levels and whatnot, I didn't care for the story at all, I basically skipped every cutscene, maybe skimming through it, but I never really took my time to read the dialogue thoroughly (refer to the "AQ being slow paced" comment). It also didn't help that I was never able to kill Slugfit until they reduced his hp, so I could barely even start the whole 13 Lords of Chaos storyline.
Even though I started out on Twilly, the canned chat was more than enough for my needs, I didn't really play to socialize to any extent, just to play the game.
I also remember I started out using my mom's email with her permission, that's how much I wanted to play. Note that I didn't need to do the whole email verification process, I just needed to type an email to make an account in the first place. Later on she found out and then told me to create my own email address. It's funny to look back at that nowadays.
Nowadays, I still enjoy the simplicity, to some extent, but because I'm more grown up now, I also care about how a game feels and AQW being simple is not a good thing when you start to want deeper mechanics.
Again, story wise, I couldn't care less, I do read more of the cutscenes nowadays, but I never really go back to it once I'm done and try to connect any pieces of the puzzle. I enjoyed the ToD cutscenes more than any other and even with that, I would only be able to tell you the most barebones explanation of the plot, it was mostly the humor that made me want to read more.
Combat wise, it's definitely more enjoyable when you have access to a lot of classes to switch between, depending on need and there's always going to be some satisfaction in hitting higher and higher numbers as we level up. I don't mind a skillset of only 4 pre determined skills, as long as classes can feel different to play and there's enough to be able to switch it up every once in a while.
The only thing that bothers me with current AQW's combat is the classes' reliance on crits, I don't like how common it is to crit, it feels like a norm and not and extra bonus. That being said, if a class is based around crits within it's skillset (take GB as the perfect example), then it's more acceptable for this sort of stuff to happen, but it doesn't feel much different than your average luck using class (in terms of crit to non crit damage ratio), so it's just "another luck using class".
