I happened to discover these two at a local EB Games...it's rather sweet for $29.99
You get the choice of:
Sonic Mega Collection PLUS & Super Monkey Ball DX
or
Sonic Heroes & Super Monkey Ball DX
The plus to this...you save $10
The con....it comes in a single disc platinum hits casing....the 2nd disc just sits on top of the other
The booklet and insert have new artwork, yet the Super Monkey Ball DX disc does not say "Platinum Hits".
Seems Mircosoft got a little lazy with packaging this one..
so what I did was find a spare Shenmue 2 case from work and used it lol
But this was nice of Sega to not even inform us of this release lol Shame shame Sega! I'll get you! *Dr. Robotnik laughter*
