I had a similar problem - our computer could handle normal Neopets just fine but the flash-heavy PPP was just too much. I do remember making new accounts a few times, but ended up stuck or running into too many features gated behind membership and never really latched on in the same way. I feel like a lot of the Nickelodeon games had that problem, and it certainly wasn't unique to the Viacom stuff specifically, but it does make it hard to remember specifics beyond "I wanted to be a Faellie and I couldn't because they used different species".

A rewritten project is great but I have to say I've been burned by them too many times - usually the team is too young or inexperienced to really muscle it through. I do hope to see something come of the project eventually, though (hopefully with less gates...).
