Yeah it's pretty much my first time through the game. Casing the Joint and Masks was quite a horrible level in my honest opinion, but I'm finally on the last level and it looks like it'll be tricky. Quite a lot of mechanical beasts about this one, though I should manage. Expert skill was the best choice to start anyhow, ha.
I even started playing the FM, Thief2X: Shadows of the Metal Age. Impressions on this so far are quite high, hopefully it lasts.
You're coming up to Soulforge in Thief 2. Prepare yourself, man. One of the hardest levels you may ever play. Hopefully you'll choose to play it on Expert...and if this isn't your first time playing Thief 2, then I'll just shut my mouth.

The 7th Crystal for Thief II is a true masterpiece. Huge, beautiful and challenging.
Hey Quakis. You'll end up liking Thief II better. Most of the levels are enormous and take me no less than an hour (expert difficulty, going for all loot and secrets) to complete, except for a select few. Some even took me over 2 hours! The cut-scenes are oscar worthy and I have a quicksave before each one. Try to be as thorough as possible.
