It may not look like much, as it looks like the old Harpoon, but the gameplay is great.
Most importantly, it's quite easy (and relatively quick) playing out WWI naval battles. While I like SES Jutland quite a lot, it is also a pain fighting with it's interface and the battles take a long time. SAI is just far easier to use - especially for larger battles. There's also been some questions as to Jutland's increasing bug issues lately and no word from the devs in months so it looks to be on hold right now, anywhow.
The campaign layer is supposed to be added in an update to those who have purchased the original. The updates have been flowing quickly and they've been listening to requests, so I'm happy with support thus far.
I can recommend this to wargamers interested in the period.
