I like this game, but I think the initiative rolls are too big since one player moves his fleet and the other player gets to react to that. If I were going to tweak the game, I would change that. Range rules would help a bit too.
I'm not sure why the designers use this initiative system. IgoUgo has a lot of problems and there are interesting ways around it. Both DnD minis and SWminis by WOTC use a 2-model activation sytem. This creates a semi-concurrent turn. I move a couple pieces. You move a couple pieces. Repeat until the round ends. Init is still very important, but there is a great deal more decision making and player interaction when you have a semi-concurrent turn.
