it takes time to collect all that trophies!! salute! yet still wondering if collecting all with gives some affect on the Digimon? Is it going to be stronger or else?
In the same opinion as you, I would like you to add development elements other than Vitals and mood.
However, if Bandai tinkers with the software of the successor Vital Breath too much, compatibility will be lost. I suspect that Digivice v couldn't be changed much because of that.
