Well, I finally got my copy.
So far, I spawned on a beach in a freezing biome. Nice landscape so far, but it was barren. No trees, so I did a bit of searching heading East from spawn (from what I can figure with the sun), and found a forest with some rather strange landscaping as well, still with the freezing biome, but eventually warmed up. I'm gathering basic supplies right now. I'll carry a pocket camp pack with me until I find a gateway. I mined out some gravel for arrow-making as well as gate sealing just in case I find one, and some buggers decide to want to jump out.
Once I set something up, I'm going to make something like a SG-1 style base camp around the portal. I'll eventually make obsidian crafting a top priority if I find a good enough supply cache to get materials from. Demon hunting and taking down the almighty ghast will be a goal.
EDIT:
Actually, screw it. I'm going to risk it with my inventory. Unless, did everyone find one first, or build one legit?
EDIT EDIT:
HOLY HELL Nether is huge. Lemme adjust my difficulty settings a tad.
EDIT EDIT EDIT:
3 seconds after adjustment and I get tons of random screams of who knows what. Could be pig-zombies. Why... why... WHY DO I NOT HAVE A BOW?!
At least I respawned in a pretty kickass viewpoint, and in case I die (cheaters never prosper), I at least placed my gate in a nice location that looked like a gate would belong. Oh, and BTW, my vantage is a good 500 feet from magma sea level. I'll try and grab a screenshot.
EDIT EDIT EDIT EDIT:
Took a couple pics, but I had a ghast chasing me and I had to dodge a few fireballs. Had to set to peaceful to get the shots.
