I only pre-order Resident Evil games when it comes to software. It's fun being a nerd and going in and seeing other nerds.
Most recent for me is RE8 Deluxe Edition on PS4, and I paid it off the other day. I want to be the first nerd at the store to get it.
Last thing I preordered was the WiiU, that was a funny launch. Gamestop catered with Buffalo Wild Wings at like 9am, lol.
My best experience was randomly getting a Wii on launch day. The PS3 launch was insane, people camping out for like 2 weeks in advance, etc. I drove to my local Best Buy the morning of the Wii launch to see what was up, as I cruised by the front door the guy at the front of the line yells, "They got 7 more systems, come on dude!" Everyone in line started cheering so I was like, "fuck it, I'm getting a Wii." Waited in line with 2 brothers who had been saving gift cards for like 2 years, dudes had a stack like half a foot tall, lol. I ended up getting Twilight Princess and since I hadn't been gaming much during that time, had zero clue was TP was all about or what the Wii was all about really. Really great experience and TP is probably my favorite Zelda game. Pre-ordering games/consoles for me is more about the experience of being around other nerds than it is having something the day it's released.
