I've heard that some people/factions have made combat simulators based on the current set of rules and suspected workings of the system when it comes out. Does anybody know of any of these, and if they are relatively accurate? Thanks.
Impossible is just a word people use to make themselves feel better when they quit!
Have a look at various factions websites - generally its the government and security type factions that have them. Are they accurate? Yes and no. The weapon loadouts, hull, shield etc values are all as in the rules. However, the amount of damage they deal is guesswork. Additionally, weapon delays and travel are in the minutes rather than hours as it will be when combat is released.
Its a good approximation, but its best not to base any future preparation for combat on them.
