I would highly recommend getting this game (and no brainer if you already own a VRheadset; i'd go so far as to say buy a headset for this game; that's pretty much the only thing i use my Quest 2 for (after discovering VR/this game with the Quest 1 in May).
First thing is that all my irl techniques transferred more or less to the game; medium speed/controlled strokes of loops, drives, chops, and various serves will come out as you'd expect irl. I was even able to youtube the tutorials of a few new serves and practice them in game, and have it pretty much work out when i tried it back on a table. This is so far the best transfer for IRL skill into a 'video game' that i've experienced and it is awesome. Having said that, if you were to really swing as hard/fast as you can on any loop or drive, the tracking does tend to break down; but as mentioned that's being improved, and different headsets/different players tend to have varying results from this.
After 4-5 months of only VR, I went back to the office and had a few short sessions at the office table;initially i whiffed some loop shots in the first 5-10 minutes of play (a slight bit of timing difference between VR/IRL), but I adjusted back to relatively good shape within the hour. I still credit the months of VR, and the ability to practice against a bot, and a ball machine (and a new feature to have the bot feed to a backhand/forehand is even better), and not having to pick up balls.. that allowed me to develop a much more confident and consistent forehand than i ever had before in my ~15 years of playing.
Also, this game has allowed me to play 1-2 hours of TT a day, against people all over the world and at any time of day. It's pretty much my only exercise in these months but has probably kept me in decent shape. It's also just super fun for a tt enthusiast.
So I was contemplating to buy this game to keep up my fitness level in a fun way.
> I'd say definitely go for it, thats what i did and the only thing that's worked up a sweat for me during this lockdown
But from your answer it seems that doing this will hurt my table tennis game in real life when I start again?
> unless you're constantly playing competitions with no readjustment phase immediately after going back to real life table tennis, I wouldn't worry about it. I play the game following good real-life strokes/techniques and the only difference is some relatively minor feel/timing differences.
