(Saw this question asked on another popular link aggregation website and it got me thinking)
If you could play one game for the first time all over again, what would you choose? This might be because you want to do it all again, or because you don't think you got enough out of it the first time. It could be experiencing the game exactly as you were back then, or experiencing a game with what you know now.
For me, it's Legend of Zelda: A Link To The Past, experienced exactly as I was back in 1991.
Nothing comes close to how jaw-droppingly amazed I was by that opening sequence. The epic orchestral score, the cinematic rainstorm, creeping around in the dark... it was a generational leap above anything I'd played on 8-bit computers and consoles, and even the Megadrive. I'd love to play it again without thirty plus years of Nintendo/Zelda knowledge, or without knowing about the dark world.
My choice, but PvE ;) I only started in 2001 post Velious, but wow that game has taken me for a ride - and I have made lifelong friends through it and seen places (London, Nottingham, Copenhagen) thanks to it.
I played on Rallos Zek where if someone is annoying you can stick a pointy stick in em, steal the pants off the body (1 item loot on kill) and watch them run off in a loin cloth. I met my wife just after the turn of the millennium. We lived on opposite sides of the country at the time. We got married in game and then later in real life and still are.
Pvp may SEEM harsh but it was a lot of fun. I still remember going to war with an entire guild spending nearly 24 hours running into a dangerous area sniper style and then exiting and cycling in for another run. I ended up dueling their guild leader and barely losing. Their entire guild had a party on my corpse. When I woke up it was still going on.
