I'll help out.
1) The species of the pet(s) you have:
Hissi, Bruce, Kyrii, and Wocky(lab)
2) How long have you played this game? Are you still playing?
I've played over 7 years (update my darn shield, TNT!) and am currently still playing, even though I've fallen out of love with Neo several times.
3) How much time do you spend on Neopets everyday? (AVERAGE)
Too much at the moment, because I'm job hunting
At least two hours, I think, but lately it's been around 5.
4) How did you get to know this game?
I can't remember, I signed up in the year 2000, shortly after it first started. Man, those were the days...I'm guessing that I was searching for "virtual pets" or something like that, because back then I loved virtual pets (remember virtual aquarium?)
5) Do you have any comments on the pet designings?
Customization is a good idea gone bad. *coughcough*. I haven't converted my Hissi for a reason. Neo, at times, seems to be losing any sense of art style.
6) Your favorite aspects of Neopets? Any reasons you like those?
It's a great time sink, and certain site events are fun. I also enjoy the people I've met thanks to the site
7) Would you recommend this game to your friends? Why?
Probably not, because I imagine it's very hard to get into nowadays...for some reason, Neopets doesn't seem as friendly to "newbies anymore, with freeze sprees and such.
8 ) Find any disadvantages about this game? Do you have any suggestions on how to improve those?
I think I've hinted towards many of the disadvantages above. I just think that TNT, in general, needs to return to the "we listen to our users" philosophy, and really take their opinions and concerns into account.
