First, this is a Really awesome game, I like it alot and recommend everyone play it. Its not a sim, but its pretty challenging.
Next these arent meant in a negative or harsh way, so Im not Griping.
1- Periscope is a few seconds too slow.
2-Wayyyy too many dead and Injured crewman
3-Launch Depth of torpedo's shouldn't be below 100 feet
4-Colors...the lime green...not very WWIIish.
Destroyers/escorts/subchasers are fun to battle.
Depth Charging..lol I swear my table is rattling.
Overall A REAL HOOT!
