I picked this up for the early access on Steam yesterday. I'm not an MMO fan, but from what I've gathered, I don't think I'll really dislike that aspect, if it's forced, when it comes to this game. I might even actually enjoy multiplayer. It was also kind of an excuse to use my PC more, because I'm predominantly a console gamer but built a tank of a PC a couple summers ago and barely use it.
Between the capacity limits and trying to address some things on my PC and laptop (and do typical adult duties around the house), I didn't get very far. I made my character, followed the professor to his lab, and picked my first Temtem. All of that ran quite smoothly with no issues, but I haven't even gotten to a battle yet.
The capacity thing itself wasn't too terrible. First time I started it up, around 5:30EST, I was around 11,500 in the queue, and only waited about 10-15 minutes. A queue of around 6,000 a few hours later took a bit longer. I read that there were a lot of connection issues earlier in the day, but I didn't run into any. The devs were throwing out updates all through the evening and early morning.
I've been looking over type charts, and the match ups are pretty interesting. There are 12 types, some of which are mirrors of the Pokemon equivalents (like Nature being weak to Fire and Toxic, and strong against Water and Earth) and some that are original, like Digital and Crystal. Gonna take a bit to learn them all, but that's kind of exciting.
I know the Pokemon comparisons are going to be unavoidable, but I think this already has enough customization options and personality that it's going to be able to stand on its own eventually, without the Pokemon crutch.
Edit to add that I was using a PS4 controller to play. I used mouse and keyboard when starting up and making my character, but quickly switched over. This isn't really a jab at the controls--I'm just not much of a PC gamer, so mouse and keyboard just isn't comfortable to me.
