Hmmm... I can yes nothing more ... than to add this: NOT only the graphics are better ... also many loot by exploring & trading is changed in de very good way and last but not least now the DKS has more balance
But I can understand your frustrations about your wasted money .. it's indeed a sad thing, but I'm sure it was because of Microsoft and the Xbox ! Plus, Divinity II is the very first game Larian bring on the market on Xbox too !
Nobody is perfect and "there's also a learning curve..." Without learning via mistakes, you never learn if you don't try and make some risks ....
