Sorry this is late, I’ve had a lot going on recently. Will finish tomorrow.

Scores:

KrAkenAtomic’s T-124 railgun

Ease of use: 5/15 - Easy to use, but has no vertical turning, slow horizontal turning, and is useless on hills.
Effectiveness: 15/20 - When you can manage to make it hit, it’s deadly, though it’s very hard to do so.
Range: 10/10 - Very long range
Looks: 2/5 - Looks great, but could be more like a rail gun by having a super fast fire rate and low damage. Also, the cameras don’t work right, they’re too high up.
Total: 37/50

WolfYankee’s M220 Self-Propelled Howitzer

Ease of use: 7/15 - Aiming’s great, and it’s cool that it’s self propelled, but it cannot traverse hills.
Effectiveness: 15/20 - Effective, but could fire a little faster
Range: 15/15 - Great range
Looks: 5/5 - Great details
Total: 38/50
