It will take me 25 years to make 1mil at my current salary, yet I'm very well off. If I made 1mil right now I'd probably be able to consider retirement, though what I'd probably do is take 200k from it to pay off the house and have some play/toy money, then invest the rest and keep working, since I like my job anyway, but at least I know that if I lose my job I'm set.
And 600 bucks is a pretty paltry amount of money when you have a mil at your disposal, even if you do decide to waste it on mac stuff.
This thread definitly has me inspired to look at making a game, either mobile, facebook, or PC. Start small, and move to something bigger, or maybe just go straight to something bigger. For the longest time I've been thinking of how fun it would be to make a minecraft like MMO. My big issue is I'm not that good at graphics though, but if you look at minecraft the graphics arn't that complicated so I could start with something like that. Use placeholders, code the logic/gameplay first, then can always figure out the graphics after, perhaps premade creative commons stuff.
