higher fame is more gold you lose lol.. so that is a fact.. to a certain point..
if i had to give some suggestions...
1) Radar is very important.
2) Ship should be big enough that you dont see the same thing every move...
3) Attack is easier to build than defense, but it seems defense pays off more.. ie level 10 defense is about the same cost as level 12 attack.. so beware when upgrading and deciding what you need..
4) Keep your fame as close to 0 as possible.
5) Don't run off your mouth acting like your hot ****.. nobody will like you...
6) Respect other players.
7) Actually THINK about what upgrades your getting... don't just upgrade because you have the gold to...
Make a map.. it will help you a lot in the long run..
9) Towns give you more gold than islands, (typically) but you gain fame from towns.. so use caution...
10) if you have 10 radar and a level 1 ship (2 moves).. if you hit someone on the outside of the radar, it costs you 5 moves... so always attack in your biggest ship...
im sure i can think of more, but im home eating lunch trying to study for a chemistry test that i have in a half hour.. ill try to think and add some more on later... hope this helps a bit
