Ohh man , finally someone doing a vr tennis game that looks like it'll be fun. Remember Wii tennis ... Fun and exercise. Good job guys. I'll be buying this for sure !!!
I don't know about the longer rallies being worth more points. Ultimately it'll mean that esüecially close matches consist of fewer rallies. It may also cause an incentive for players to not play too aggressive at first, in order to raise the bar to at least 2-3 points before starting their play. From what I've seen in different eSports you'd want to have it the other way round: matches between equally skilled players create the most excitement and should last the longest. Matches with a clear skill difficulty should be over quickly.
I like that rackets can go through walls otherwise it may feel too boxed in. Can the rackets also go through the floor? Ultra rally also sounds really interesting. Will Racket Club be free-to-play like Ultimechs and Blaston? Resolution really makes a lot of cool games.
