I have to say thought this specific mario tennis game looks very promising. The gamecube version was pretty fun back in the day.
Might be tempted to buy it on release
You can use a gamecube controller wich works very nicely with this game like mario power tennis not to mention that the gameplay is very solid
The music is fire

Mario tennis is way more fun than any normal tennis game there is no comparison really.
A realistic tennis game plays less smoothly making it more realistic not to mention no gimmicks or special normal moves added etc Presentation visuals and music are also pretty boring for my taste just like a real tennis match on tv. Mario sport games have a more arcade like feel of play while real sports games try to immitate the the real thing like your actually watching a real match on tv with the difference that your controlling the characters on the screen.
