World of Warships on PC is one of the most popular games available, from start it amassed more than 50 000 000 players around the globe. Gameplay is about naval battles of historically accurate ships where tactics and strategy are key to victory. Such legendary vessels like battleship Yamato, Iowa or Błyskawica destroyer are waiting for you. In newest update there is a lot of technical aspects improved (ex. water looks and waves) so game looks better than ever before.”
 
My thoughts:  The prices are decent plus the in game bonuses.  50M players is an impressive figure.

As an alternative, you could always make your own.  I have thought about doing it, just haven't yet.  There are quite a lot of custom pad printers out there.  Here is an example: https://printyourpad.com/.

Thanks for really helpful guide. 
I researched a lot about mouse pads and I love a customizable option in mouse pads. Most companies offer make your own mouse pad and it is really a good option. I recently ordered a mouse pad from strumace mouse mats and I liked my mouse pad Quality and design.
