Writing exercise.

Dear Alex:
It was great to hear from you. Let me congratulate you on passing the exam.
To my mind I think you should buy a computer game because it is more funny more fun and cheaper.
You could buy Call Of Duty. it has great music and an incredible graphics. Also You can also play online with people from all over the world and the best thing is that you can be talking with to others players while you are playing.
I hope that I've helped you my suggestion helps you make a decision. 
Hope to hear from you soon.
Love
Chary.

What do you think about this letter? Is it good? Thanks for the help.

PS: When you say something is "funny" like "this is a funny show", it means the show amuses you or makes you laugh. But when something is "fun", like "it is a fun game", it means it is a game that entertains you. Aside from the minor mistakes, it's a good letter! ^^ (I agree, COD is pretty fun hehe)
