I currently doing a playthrough funnily enough, didn't realize it was so close to an anniversary.

I've been spending more time exploring and doing side activities this time around, just driving around and taking photos. It ended up being quite a surprising experience. I was surprised with how easy the game is, how fast the story moves or how empty some parts of the world are (makes sense considering when it released). Taking the world in a more touristy way was an interesting change compared to how I experienced those games before. It's also a way of playing I've been trying to move towards more and more recently (doing the same with Cyberpunk as well).

I still think it's a great game but IV and, to lesser extent, Vice City are probably my favorites as far as mainline games are concerned. IV especially as it had a nice grounded approach to gameplay with weighty movement, interactions and driving, as well as the story - it sucks most people hated this as GTAV ended up being a rather mid experience for me.
