Wall of Force IS quite nifty, ain't it?
Hey, Ea, which of our systems were you disagreeing with? Was it my (ECL^2)*10000 system, of UK's multiple system of (ECL^3)*100 and (CR^3)*100?
I do believe that UK's system is way off, as it gives too much wealth of any sort to characters of Levels 100+. By the way, UK, there is another reason I do not like the system you proposed. By your system, a character at Level 80 will have the SAME amount of personaly equipment as someone at Level 87, which I think highly inaccurate.
If you made some special calculation that would take fractions of a CR into account (such as ECL 80=CR 40, ECL 81=CR 40.125, ECL 82=CR 40.250, etc.) for purposes of determining wealth, then your system may be able to work, because the personal equipment numbers would be close to the numbers that I got, if not lower, which would balance things decently as long as there are new feats that can emulate some magical item powers.
Moving on to the SR, I have agreed with Ea from the beginning. Take for instance a Level 160 character, who is CR 50. If he tries to cast a spell at a Level 175 character with SR 185, he has almost no chance of breaking through the SR, and only a minimal chance with various feats added. Another level 175 character with the same feats, however, would almost never fail in breaking through the SR. Yet these two are the exact same SR.
This means the whole system breaks down once you're in triple-digit levels, even though it is still starting to break down around Level 50.
What I have proposed is make all caster level numbers for SR a function of CR instead of Level. Base all SR on the CR of the creature (for instance, make a Great Wyrm Prismatic Dragon SR 50 or so since it is about CR 45). Next, make the caster level check for penetrating SR based on the CR of the spellcasting class (a Level 100 Wizard is CR 42, so the check would be 1d20+42). For multi-classed characters, take the CR function of only the spellcasting class (for instance, a Ftr50/Wiz100 would still have CR 42 in the spellcasting class, and thus make a check at 1d20+42, regardless of when those wizard levels are gained).
On a side note, I highly suggest doing the same thing to dispel checks. If you don't, a CR 50 Level 160 Wizard would have no chance of dispelling magic cast by a Level 175 Wizard, despite the CR being exactly the same. Basically, make all caster level checks a function of CR, regardless of what the check is for.
Note, however, that the actual caster level for spells is still the level, so spells wouldn't lose any power under this rule.
By the way, UK, I posted a question for you on the Saiyans thread. I'm still trying to perfect things, you know how it is!
