Short, repetitive, boring & dull.
There's no more than 3 "mission" types they just repeat themselves over & over & the unskippable cutscenes are awful to have to witness.
Once you complete the story (which will take 3hrs max) there really is not much else to play for but shamefully easy achievement points.
You could collect never-ending little crests or join either the Duelling, Potions or Flying Clubs, but quite frankly why would you wanna bother joining these Clubs when these 3 things are repeated thoughout the game to the point you're sick of doing them.
The scenery is just taken straight from OOTPhoenix, so if you've played that it's very familiar, out of the 2 of them I'd definitely say OOTP was better, this just has nothing to it.
It's a very poor offering, don't waste your £, the producers should be ashamed of offering such crap.
