Differences in TW200 & 2300AD combat

[StainlessSteelCynic]

Keep in mind I never used the T2k 1st Ed. rules so I don't particularly remember much about them except that it used percentile rolls to determine success/failure.

2300AD had a rules system that seems like it was the prototype for the T2k 2nd Ed rules. Main differences were that even though there was a difficulty level/task resolution system akin to T2k 2/2.2 in place, the outcome was also subject to die modifiers that could add or subtract from the die roll.
2300AD also used Coolness Under Fire.

I can't think of much else without dragging out the books but I sort of recall that my overall impression was that it would be fairly easy to convert weapons and equipment from 2300AD to T2k 2/2.2 rules because they shared some similarities already.

Edit: firearms didn't have the range bands that 2/2.2 does, I'm pretty sure they just had a max effective range listed.
