Is it okay to play video games as long as it doesn't take over your life?

Ive been playing video game since i was 5 yrs old well im 18 yrs now ive been going to school (community college) and looking for a part time job also going to take my driving test soon! I don't stay up play video games i got stuff to do! I workout 6 times a week im actually doing a 60 day workout program call Insanity now im eating healthy now! Well im trying to say is playing at least 3-4 days a week at least 3-4 hours a day not that bad to play video games! im mean it's just an hobby and wish i could find a career in making future video games, i don't think it would be for me! is playing 3-4 days not bad cause i got so much stuff going on in my life. i never had a gf sad i know been on a few dates but nothng serious i dont play to go serious until im done with school and what not. sorry to get off topic so is it okay play video games as long as i don't over do it and mix it up with other hobbies? i use to have a xbox 360,ps3, and a wii but all i like portable gaming hahaha idk cause is its portable! the thing i find funny is that i dont bring them anywhere unless im on a long trip. thanks sorry for all this blabbering and what not!
