As a PMD fan, I highly reccomend to you Bespinben channel. Or Glaf Glorf.
The former leads the PMD GTI piano arrangment project and the other reorchestrates various songs from the whole series. Then there's also Gryphus Meli, Duskpiano, threelines3....
I'd say threelines3 is the best arranger of them all.
I just spent the last hour playing World of Tanks for the first time, just so I could input a code. It turns out, I needed to play World of Warships, not tanks! I am so mad at myself right now. And the worst part is, I found out the code doesn't even work!
