No man , i have both A6.22 and A6.60 , and more or less u can do the same with both. So , to really answer you , for a hobby , you really only need like A5 , LOL, so u dont really need to update , however , I usually keep a stable version and an updated one all the time on my pc. I used to alwasy have 6.31 and another with latest update , when down to 6.22 to be able to use DX8 for making casual games , so now i always keep 6.22 and a fully updated version in case I wanna experiment with new features or something.
