Technically the tracking area is unlimited in our current solution. Though, speaking about LBE (location based entertainment) - this is retail business and one of the most important KPIs here is revenue per square meter. And having 100m2 playarea (i'm not even talking about bigger ones) - is a tough challenge to be honest. You must be SO much better than any other VR arcades to justify much higher price people have to pay.
Speaking about VR paintball/ lasertag - thats pretty obvious conception and there are a lot of implementations on the market. Noawadays its getting even popular with Oculus Quests. Though for me its not that interesting as VR have much more to offer, we just need to reinvent game concepts :)
