#1: Better Graphics
The bottom picture is of Sensitive Serena(Serena is the name of my IRL
cat - yes, I now have a kitten and she loves torturing me while I play
computer games and sleeping behind my computer) in Pirate101. The top
picture is that of Sierra and Katie having a "talk" and OMG those two
look hideous compared to Serena!
Welp...

They heard me.
The Summer 2018 Test Realm includes a full HD upgrade for Wizard City as well as "talk" animations for NPCs. I am pretty sure they are going to do better now. Still waiting for the upgrade to pet training, but they also included a new "photomancy" User Interface so you can take more dramatic screenshots...

And now Monstrology has more monsters you can steal animus from. Yep, three new Monstrology essence types were added in the new Test Realm - Manders, imps, and elephant-type enemies. It's not 100% better but I am glad they chose Manders and Elephants as new enemies to give for house guests. I can now upgrade Katie's House of Monsterdromes to 2018. ^_^
Thankfully I got my SSC check this month and July is a dry month for PS4. ;)
So yeah, 2018 is going to be a Christmas in July for me as I return to Wizard101. I am going to buy some time for Sierra Fairyfriend and Katie Ravenpetal and check out the Test Realm.
