^ totally worth it, best game I have played this year by far. PC port had some problems initially but is fine now. AC4 on PC will be cheaper though, its dropped down to $35 a few times and will probably be $40 or so in january sales. there is a ios/android app you can get which is very useful/fun, and an online website (
Assassin's Creed Initiates) that pours an insane amount of backstory and stuff into you.
AC4 does play through uPlay, the steam version just launches uPlay basically, so if you refuse to install any other launchers keep that in mind. the uPlay integration is pretty tight, and required to access multiplayer stuff and kenways fleet (sort of like the ac2 "send assassins out for money" part, except with ships trading now).
for those that have ps4's, don't starve is free in january with ps+ fun game, although you get a bit bored after a few hours
edit: AC4 for PC is $35 on amazon right now, so you will save $10 buying it there rather than steam. the $20 season pass gets you the 1 single player DLC and some worthless MP stuff (costumes basically) and the kraken sails/masthead/wheel (worthless) for SP.
also a couple of friends have recommended sang froid, a strategy/combat game involving werewolves, setting up defenses during the day and killing them at night. its $3.75 on humble today $15 normally
The Humble Store: Great games. Fantastic prices. Support charity.
edit2: if anyone wants to trade snow globes, I have an extra snow globe #1 and #6 and looking for #7 and #8. add tearsintherain to your friends list and we can swap em
