Yeap, the game is based on V-Pets, and Digimon are creatures that need to fight in order to keep on living. You could ignore PVP if you wanted to, but you wouldn't get past Numemon each new gen, and you wouldn't be getting bits for items. What makes you avoid PVP in regular games? Maybe Net Driver is a great opportunity to give it a shot!
No Problem with fighting, quite the opposite. I can Grind for hours in any given RPG, I simply strongly dislike PVP. I hate any form of "Meta", of having to either wait on people or deal with them being absolute dicks, on them quitting half way trough or Min Maxing everything, pretty much meaning that creativity is getting axed. PVP in everything outside shooters just fucking sucks and takes the joy out of every game that forces you to partake in it.
