A M!X is about two Domino's pizzas over there.
Shall we list the pros and cons of a M!X compared to Domino's pizza, like some guy did with Sonic Boom and rocky road ice cream?
Let's see... a pizza can be shared with friends while a M!X cannot. A M!X can produce offspring while a pizza cannot. A M!X is made for kids while a pizza... is made for all ages? You can log your adventures and the growth of your M!X... I guess you can log your adventures and the growth of mold on your pizza?
Tamagotchis can get a bit boring because the main attraction of them is the fun of raising an animal. Part of that fun comes from the bond formed between the owner and their digital pet. If one has a hard time bonding with their tamagotchi, the devices lose allot of their appeal and can seem like pointless games. Thus, sort of in line with Jhud's remark about role playing, having animations for the locations gives the feel that the tamagotchi and the owner are sharing an experience, rather than interactions like playing games or buying things which limits the experience to being the owner's alone. I suppose allot of that is a matter of interpretation but the little things can have a big impact, even if it is all unconscious feelings.
Contrasting Tamagotchis with video games is only partially appropriate as on one hand Bandai should aim for making the process of raising an animal (or alien, they're technically aliens) fun, yet Tamagotchis can be considered a separate genre of games. Just the same as some people go nuts over first-person shooters while other people hate them, or some people just love dress up games but other people find them so boring, some people really enjoy Tamagotchis while other people don't. Maybe you, Indialien Jones, would prefer a virtual pet that is less simulation and more achievement and collection oriented, not to imply there is a problem with that as there is always room for improvement (and I can think of a few points myself).
My p1 offered more nostalgia and fun than the M!x.
I find that certain people prefer certain "generations" of Tamagotchis more than others. Some people really like the colour Tamagotchis while others prefer connections, and still others collect only the vintage models. Each "generation" has it benefits and detractors and while I sort of grew up with the connection models, the vintage models have a soft spot in my heart. Part of this appeal comes from how I have seen others treat the vintage models to the point the characters on them have an iconic status. Another more tangible part come from how the vintage models are designed to have a complete life cycle which makes them seem more real as well as make each "generation" special and unique. The vintage models don't make it seem like a tamagotchi is just another number in a generational chain. Yet there are ways to use the more modern models to get a similar, but different, affect of the originals. They all have their benefits.
Additionally, there are more virtual pets out there than just Tamagotchis and there might be devices that have the best of both worlds. The big problem is one might have to do allot of the figuring out themselves and might find a few duds along the way.
Let me just state again that there is always room for improvement and with enough time and experiments, Bandai will probably come up with an idea that revolutionizes Tamagotchis into something outstanding.
