I was daunted by it at first as well when I got my hands on my deck. I didn’t want to break anything. But I tried it at some point and can’t recommend it enough! There are plenty of good tutorials on YouTube (that take just 5 minutes) and they also made the process of installing easier since when I did it. So if you’re on the fence, I’d recommend just to go for it, it’s not as techy as you might think.
Yeah, it was the same for me. I loved playing the demo on the PS3 back in the days. You can actually get it from key resellers which is what I did. However, I think they sell for about 80€ or so which is insane. I thought it was expensive when I bought it for 30€.
