not compulsory, but highly recommendable.. and i believed the ones that are important are your game design portfolio, and the other 2 essays...? and a personal statement? Just follow the list of things that are required for the BSGD and u should be fine... i think.
ritsuko: i'm guessing you're under the BFA course? ;P
Haha, RTIS.. is the BFA 'expensive money' forums / website still up?
"is their course recommended for people that of engineering background ( diploma) and looking for a mid career switch? my current job ( or industry for that matter, harddisk manufacturing) future is very bleak. not sure if i'm suitable since i'm already 30, and have no prior knowledge in this field"
I don't believe there's any age discrimination, we have freshmen in RTIS that are near 30 years old as well. It's really up to you, but the full time degree will take up 4 years of your time, during which you won't have much, if any, time to work at all.
There are continuing education courses, but I can't really comment on how relevant or useful they would be to you.
