Thanks for starting up the guides fellas. Mark I know I've used yours before and they are top notch. BAR4D I think I've used his guides too as the name sounds familar. Either way I know it's a monumental task and we all appreciate you for it
Glancing over the achievements, it doesn't seem any are missable, which is nice. Can just play how you want and go back and gather the remaining achievements at your leisure.
