This will help set a mood for the games. I would really enjoy this.

Please allow us other choices for skin aside from grey text and light text on a white background. Grey text on a white background is something very trendy with web designers because people think it's "clean" but the low contrast is also hard to read for some people.

I'm a user with Irlen syndrome and reading text on a white background causes letters to shift, blur, and the white to jump out at me. I use accessibility tools to change the backgrounds of webpages but they do not force other colors of text. Colored backgrounds also help users with ADHD as well and are easier on the eyes.

The result of forcing the white backgrounds on all pages to #705fa9 is that all that light grey text is extremely difficult or impossible to read. On this very page I cannot read the "shared this idea · March 03, 2015" text, the "general" category on the right hand side, or the comment count on the page, and the messages written by other people are also barely readable without highlighting.

A user who cannot read your website without strain is a user who probably isn't going to pay you money for the service you offer.

Allowing users to choose their own background colors and a preset range of text colors (between black and grey) on their own side would make the site more accessible to individuals with visual, perception processing, and attention disorders. Alternately, allowing users to have their own custom cascading stylesheets is an alternative, though you should have the stylesheet automatically populated with the default information so they don't have to thrash around blind figuring it out.

The universal grey background does get boring after a while. Each character's move can be a different colour, possibly helping the split-scene scenario.
