Bought the game, played ok on my desktop, but not that great on my laptop.
It was priced EUR 24,99 or something and with a 10% release discount at EUR 22,50
Although I do not often refund a game it somehow just missed the mark to keep it.
The gameplay is exactly the same as the IOS version, which is good.
On my desktop besides some minor issues it looked a lot nicer and than the iPad version.
IMO the title should have been released as Early Access sub EUR 20,-
The gameplay is nice, in a some way I would have enjoyed to continue playing it. The way CB4G captures naval combat is interesting, managing your carriers, when and where to recon, keep a strike package on deck? Etc. If you make a mistake you pay a big price.
I may revisit after more patching, the developer is an enthusiastic guy.
OTOH - at first I wasn’t happy with LnL Nations at War at release either and also choose to refund - later I picked up the core game again to give it another chance, I liked it much better the second go and bought the packs again.
If it didn't run well on you laptop, try playing without the sea/lighting effects. Also, does your laptop have an integrated graphics card? If it does, make sure the game plays on the "real" graphics card. I had that problem in beta testing.
