Actually, if you started with 1e it is, just a bit harder to remember that a fireball now does 3d6+INT and is burst 3 (and that, rather than increasing it as you level, you later swap it out for Combustion or something), than it is to remember that a Fireball does 1d6/level and has a 20' radius, base, roughly conforming to fill 33,000 cubic feet if that radius is not available due to the restricted space of a dungeon made up mostly of 10x10 corridors. Why? Because when you're 14, your mind is like a steel trap - and by the time you're 41, it's rusted shut.Huh... it sounds like your'e complicating things for yourself. So what if you need to write down the text of your powers? Is memorizing Xd6 for Fireball, where X equals your level, any more difficult than simply figuring it out before the session and writing it down?
OK, that's just exageration for the sake of the metaphor, but it really is easier to remember random trivial details of a game you loved when you were a teenager, than it is to remember details of one you played last week - even if you still love it. Just the nature of human memory, I guess.
