Okay I actually started playing it (damn you
pakoito I'm supposed to be finishing the XPiratez LP
) and it's really fucking addictive. You can stack multiple carried items on a single pokemon during the run to create some seemingly unstoppable monsters. I had an Articuno with 2 shellbells equipped, lifestealing 1/4 of the damage it dealt, with just all the fucking drugs pumped into it and holding like 2 of every berry. Which will, of course, get stopped by the one thing you didn't think of after murdering your way through over a hundred varied enemies. Once you find the map item (fairly common) in a run, you can pick your path to either avoid types that will wreck your team or hunt for ones you want to add. Once you get further in the run enemy trainers start having crazy piles of items as well, and it feels all the more satisfying to beat some overpowered bullshit enemy with a bunch of cheater buffs by finding it's weakpoint or bulldozing it with your own overpowered freak. And of course the collectathon aspect is in full force, even stronger really because you want shiny versions (they give extra luck for drops) and egg moves and good stats, and the right nature and the right ability to all line up for the perfect starter, and you can't just target breed them that way like you can in the normal games, so those gacha tickets are always exciting. You also get to add extra perks to them by using or capturing a lot of a pokemon, in the form of making it cheaper to bring along or adding an extra ability.
My only gripe is that it's very hard to do a clever teambuilding thing early on due to lack of options, and you'll likely spend several runs fighting the same lame ass rats and shit over and over, because all the fancy types like dragons and psychic are in the much later areas, and harder to catch. Still, it means I ended up experimenting with shit I'd have otherwise never considered, because I happened to get an egg with a good move or that has a rare type. One of my best right now is a lame ass fat bird wearing an eggshell. It got an egg move that does massive fighting damage that scales with defense, letting it sweep the early levels filled with normals and later by setting up defense and sweeping everything. OTOH I'm also working on making a great Abra because it's my first favourite and makes a great sweeper in general- having it go from finally accessible but with shit stats, to having a good passive, to decent passive and stats, and now with a good starter move too feels very good.
Oh, one more gripe: a lot of pokemon kinda rely on common TM moves to make them good, and well, there's really no such thing when you're getting a chance of a chance to get any TM your team could use after each fight. I've never seen fly in all my runs so far, even though it's the kind of thing you'd slap on any flying pokemon and make them instantly viable. Since you also don't have an inventory and need to use or discard items as you find them (which I didn't mention before but makes trainer battles much harder) you also can't find a cool move early and hunt for the right pokemon to give it to.
