I beg to differ: I do think the physics are wrong. The towers topple over for no reason at all. Just to see if I was write, I used all Green square blocks and built a tower to a height of 260. Then, I added one up-straight purple, and woosh. The purple falls, bringing down tons of others blocks along with it.
To get the badge, first go to the house close to the sewers and get the quest for the lead pipes. Once you have enough, take them to the guy and you'll get the badge as well as a reward.
Engineer- By far the best class. By FAR!! By the farthest landslide in history.
Psionic- Seconds best class with a huge gap either way
Juggernaut- By far the worst class.
It used to be good but the Grand Exchange, Fair trade, and no Pking made it terrible.
GE made stores obsolete, leaving towns deserted. Also, you were pampered beyond belief. You had to go to one place and type in whatever you want, instead of looking for it.
Fair trading took away the point of trading and merchanting.
Bounty Hunter was stupid as the craters are stupidly leveled. If you're level 56, you stand no chance as stupid 90's are running around in the Medium Crater.
I agree with MrNobodi. Being an Engineer, even the first boss took several tries. However, I easily finished the game as a Psionic with only having to restart with a boss once. Being a Juggernaut, it did take some effort but I coasted along as well. Hope for more classes in the sequel! Also, the gameplay is more of a clickfest with normal enemies than it is strategy.
