So Microsoft went all official with Windows Phone 7 at their launch event yesterday, and one of the big things with Windows Phone 7 is of course Xbox Live for Windows Phone 7, something that will no doubt places Microsoft in a better position than most mobile game platforms.

Word is that Microsoft has a nice strong line-up of mobile games for the launch of Windows Phone 7 which includes the likes of Need for Speed, The Sims 3, The Harvest and Rocket Riot, and the guys over at Engadget have done the deed and come up with a few video previews of the games and the Xbox Live Hub.

In all there are four videos for your viewing pleasure below which in total lasts a cool 23 minutes so you’ll need to set a bit of time aside so you can enjoy them to their full. The guys say the games play and look just great, but on the down side everything seems to take ages to load.

So I’ll just stop right there and let you skip on down to hit those play buttons and check out what’s on offer with Xbox Live for Windows Phone 7, and feel free to let us know what you think by posting a comment…enjoy.
