Happy!

i have to admit, the day when Cliff lauched the trailer of for Gears of War 3 was my the happest day in of my life. I almost burst into tears at that time.
If Sega released some new information of about Shenmue, i think i can die without any regrets! Last year is was the decennial 10th anniversary of the release of Shenmue 1., i I don't know how long I must i wait for the sequel, but . But i hope it happens soon! i can finally meet the day!

No one really uses the word "decennial", even though it is accurate.  Also, "meet the day" is not an expression anyone uses.
