Where can you find mobile igre (Croatian for games) for your Nokia n70?
I'd recommend Zedge which has 718 mobile games you can download specifically on the Nokia n70; though it is ad supported.
I tried it with the game Funky Monkey in Funky Monkeyland because I empathized with a main character that's actually as hairy as me.
All it took was downloading the igre/game directly to my laptop. From there I just had to transfer it to the Nokia n70 and could begin playing all the monkey goodness. You can check out other nokia n70 igre here, though as I said before remember that your phone's data connection will download new ads every 4-5 times played.
