EDIT: This "my posts are coming up blank after I type them" is really about to make me cry at this point. I don't know why do I even bother making lengthy posts anymore...
Anyway...
Since I've played Digimon Story Cyber Sleuth on my Vita, I've been interested in Digimon, especially since considering my Tamagotchi obsession I thought it's sacrilegous that I haven't had a Digimon yet. I also watched both season of the anime (with subs) and I LOVED it. Please don't ever watch this anime with dub. It really takes away the whole drama and characterization. Especially the movies. They made all of the movies into ONE movie and ruined it, especially the music. Digimon music is BEAUTIFUL and I really wish anybody could watch the anime, even if you're not an anime fan.
To my knowledge digivices are different from the v-pets, as digivices are often pedometers. And it's true that the original v-pets are rather pricy and you need at least 2.... that's good that we got the 20th anniversary edition v-pets, then.I got mine not too long ago and I'm in LOVE. The 20th anniversary improved SO much. You can raise Digimon from all versions of the v-pet (there's over 100 of them), you can raise TWO at the SAME TIME and the battles are completely in-game. You can even battle with them online via D1 Grand Prix using a password. I REALLY reccomend this version. The first wave is pretty pricy on ebay, but the second wave is a bit cheaper, about 60$. It's way more exciting than your usual P1-P2, so it's really worth having. And the only thing you'd need more than one for is to unlock the special Digimon which needs you to connect a few times, but honestly it's fine without it, it's just one out of 100's obtainable Digimon otherwise.
They're also releasing the 20th anniversary Pendulum, which to my knowledge isn't much different from the v-pet, but it will have all-new characters and can connect to the v-pet. I'm definitely getting one if they won't be sold out on Tuesday...
