It's not the 1980's like when your 64k of memory had to be used to the extreme. Yes, it waste some memory, but with today's machines, its not as big as deal as you are making it out to be.

But, if you are very anal about memory useage, by all means, don't use that method.

It's just a possible method, and of course, most games will never have like 50000 entities either. Probably more like 500 entities in game at once at most. If you want to worry about memory more than functionality, be my guest.

I can also go back and write games in machine langauge again also like the old days, but I prefer to use higher languages now, even though machine language is much more efficient.

I know, post is worthless without pics.
