it might be good to have the ability to instead of going straight to camp and not given the option, to train terramon that are lower level or don't get a decent chance. I mean I have to run to camp press f1 to renew that level of the training since the exits are blocked off somehow. the door chimes but won't unlock.
Maybe we can trade terramon in a trading post based on rarity, or whatever to gain equipment only tradeable. that to is a good thought.
another idea to put on your list of to do may be to allow us as players to capture legendaries, mythicals, and more. whatever you want to call them. in pokemon, there were originally 3 legendaries, fire, ice and zap.
I'd like to see the equivalent here too.
mons with volcanic moves or something like that because they live near vents, stuff like that.
it might be nice to encounter npc trainers, who can both trade, and duel, or offer helpful advice.
or be guided through areas particularly nasty with traps, etc for a nominal fee or based on a trade for a terramon the person has.
also collecting objects for the journey, for research equipment, equipment the trainer can use, might also be a consideration while exploring the vast underworld of the utopian world.
