Some keywords comparing original Ego Draconis with remastered DKS are :
smoother, better graphics, more balanced, replacements of enemies and loot, better loot & Armour Sets (also in the first part of the game!) ... more fun and replayability value all this give!
And also (for the Xbox version, I don't know if the PC version has changed on this?): much better "controls/interface" !!
All in all certainly MORE than enough, I can't say it "enough" times

, reasons to definitely play the DKS again (more than one time) from the very start in Farglow !!
Have Fun with the Dragon Knight Saga !
