Personally, I would definitely have to say that it would be a close tie between Legion Saga II and A Blurred Line. Both these games were brilliantly made, but I could play A Blurred Line for hours and hours, days straight. (Also, you could have played the A Blurred Line remake) A Blurred Line was definitely a well crafted game... As was Legion Saga II, but I believe Lysander put more thought into his game.
However, I can't say I'm not in a state of hype over the fact that Legion Saga R (Rm2k3 version of LS1) will be a downloadable demo version in a few months.
