No you are not. Kirby in particular really reminds me of a PDP character, Lip specifically with the brown hair and the wand and everything, although I'm sure he was supposed to be "copying" the girl in the commercial.
...Stop cockteasing us already, Nintendo. ><
I dunno about the RPGs taking a while part. You could knock something out in RPG Maker pretty quickly, although it probably won't be very good unless you're well-versed in the Ruby scripting language (or find some off the internet).
I plan to do it all in HTML5. Although, I COULD do it in RPG Maker XP, I do have experience in RGSS (because I played around with RMXP a lot). The issue with an RPG taking a lot time to develop isn't about the engine itself, though. I've got most of the engine ready to go. The issue is length; that's a lot of stuff to program through and plan out.
A puzzle game, on the other hand, is a bit different. Once the engine is ready, you just need to design the menus and the basic gameplay and you've got it pretty much setup. The rest of it can be expanded on later. If you want to do specific things, such as new game modes, or redesigned map layouts, that can be gradually extended. An RPG is harder to handle, to really be able to put out an RPG it really needs to be fully completed.
A puzzle game just needs a basic time trial mode at first. It can be expanded to have new modes later, but time trial is all you need for a proper puzzle game. The problem with RPG's is, again, the length. The entire world needs to be created, playable characters need to be configured and giving proper stat boosts, it needs to be played through several times to properly balance everything out, etc. There's so much more to do with an RPG than a puzzle game.
As for things like music and graphics, I'd probably resort to Open Game Art for that. I've already found tons of great music.
