A New Macbook User

Hi,
I am the owner of the Macbook pro retina 2,3 ghz which I finally got it and also checked it:works perfectly fine However there are some questions about since I am pretty new to this.

1)Do I need an external driver or so to play games ? And also how can I download steam and am I able to download origin too ?

2)What are the suggestions for me to getting used to mac since I am a windows user for 7 years.

3)What are the applications that you would recommend ?

4)Will the games like Civ V and the sims 3 with few expansions would be tough for my computer ? I want to use it as looooooooooooooooooong as I can so what would be your suggestions ?

Thank you

 

Hi all,
I do have a queston because I am pretty new to my computer.First of all I am feeling myself quite lucky to be an owner of a perfect computer,works smoothly however those questions came out to my mind.

1)First I decided to check If the computer is working at Apple Store New Haven.There were no sounds at all but when I go home and started to setup a few days later particulary because of my studies It started with a voice It was like 'If you know how to set up your computer...' is it a problem about the audio ? I must say that the audio was perfectly fine I watched youtube and stuff and It was a real music experience.Since I put this to the program office I had a weird idea of someone changed my macbook )

2)For the first time is it normal that 5 hours of battery ? Never put it to the charge.

3)I choose my country as Turkey since I wanted to use the keyboard of my country and stuff however I cant seem to use my 100 $.What are the ways that I can do ? I am thinking of opening an apple id from another computer and click to the USA and then buy it from there and download to my own computer

4)And I tossed my macbook pro to the wall since my room is so tiny and so many shipments arrived that there was a tiny voice not so big and not so forceful.May this cause a damage ?
Thank you
