Tried them myself today. I agree that "Polar Bash" is a bit crap - its hard to even get twice your bet back and the music is well irritating. I quite liked the "Medusa" theme graphics actually - but the gameplay is inferior to "Dragon's Loot" and its not a "sticker". And while "Little Chief Big Cash" had a poor theme IMO, it's very similar to "Glory Of Rome" with a couple of subtle differences in the bonus round - and 10 more paylines of course

And I agree - cant see I'll ever go back and play these unless I was well bored lol.
