TL;DR: If you like SoL Anime and cute girls doing cute stuff then this might be a good sequel for you, but if you expect more plot and development, then you might do well on skipping it.
Honestly, some episodes could have been easily bundled as OVA's on a BD release or something like that since they are not that necessary, but considering than the actual plot of this show wasn't that big, I guess it was needed in order to expand it to 12 episodes.
Lets get to the details!, New Game!! starts off giving new roles to the staff as they interview their employees of what do they think of Eagle Jump and what are their goals now, while they decide what ideas are good for a new game. After settling up their roles and deciding the lead, we are set up for an incredibly slow and boring plot progression filled with "cute girls doing cute stuff" for quite a while until the plot finally starts moving somewhere. Here we will have some clash between staff members, some rivalry feelings, the need of improvement their skills, etc. And then, when the new characters are introduced, the plot finally is heading somewhere after 7 episodes. You see, I couldn't even properly explain what this second season has to offer, because on half if this season there isn't much to say about rather than just cute girls on their natural environment, the slow pace for the story doesn't help that much unless that you want to see cute girls doing cute stuff rather than expecting a plot. 6/10
The animation department of this anime is probably the best thing this show has to offer, watching girls dealing with bugs or being creative with their job is quite a nice watch if you are into gaming stuff, they make good use of the definition of game physics when it comes to animation. I'm not gonna bother that much with the character designs since they don't have major changes... maybe the inclusion of new characters, but that's pretty much all. 7/10
I wasn't originally a fan to any OP/ED of both seasons, but is not like they are bad, they are just not of my taste, its okay overall. I do feel that the soundtrack on this second season didn't have that much of an impact, well, I guess that on few scenes the soundtrack was good but not enough to be completely meaningful. 7/10
Characters, like the plot itself is also one of the lowest things this anime has to offer, there isn't much development aside from few characters that had some development. The inclusion of new characters isn't that meaningful, but it helps to add more drama, comedy and fan service to an anime that were overusing the same cute formula over and over again. 6/10
Now, even if I said that the show was a bit boring and has a slow pace, it manages to give me some laughs and making me smile at times, it might lack on plot and many other things, but if you don't actually watch this for the plot, you will probably have a good time watching this for moe induction. 7/10
Now don't believe that scores of 6 or 7 for this anime is hating on it, I actually believe that rating this more than 8 is actually overrating a show that doesn't really improve that much and just offer more of the same. I do think that they just didn't want to risk that much and decided to KISS (Keep it simply stupid) but that's okay if the goal of this anime is to please the fans by giving them more fanservice and farming the money out of them. a 7/10
