In my opinion its probably not worth a life time sub given that you cant predict your financial situation in 3 years time. You also might not still be using it in that time or regularly use it enough to make the sub worth it. With the amount of content available you’d have to constantly be using it. Realistically speaking a person would only be interested in so much content, ie whats the purpose of buying a whole ware house if you only use the front 10% of it.
I’ll always advocate for getting the scripts and videos for your own safekeeping cause you cant guarantee that those scripts/vids will always be available esp since SLR has removed content before.
If you just want to stream and look around, it might be worth getting a month sub or w/e and just checking out what they have if you don’t know what you want.
There’s honestly enough content on this site for VR that might also not be on their site that you shouldn’t have to spend on a life time sub.
Also specifically for the OSR2, since you’re multiaxis I don’t think there’s enough handmade OSR2 content on SLR(if any) since from what I know Handy and other single axis strokers were the main use case(esp since their own device is gonna be single axis). You can turn the single-axis scripts into multi-axis but that is more interpretation/simulation using the single axis rather than true hand-crafted multiaxis.
