I've missed our conversations, it's been way too long.
Hmm, sort of stretch out the attack table, then swap out the A-E results with the actual A-E crits, add them together and thus one roll?
I suspect you might find that you either signifigantly reduce the variations to fit the space, or you may need a lot more space for results than you'd think.
I'll arbitrarily pick Broadsword vs AT 12, let me pull my AL (RMC version, it was on top)
there's 93 results on the table, of which:
9 are 0s
27 are hits only
13 are As
14 are Bs
13 are Cs
9 are Ds
8 are Es
Hmm, not actually all that far off, but issues.
There are 19 results on a crit table x 5 = 95, but 11 of the slash table are just hits so call it 84. 56 of the attack table are crits, so you're going to need to do a bit of inflation, like 50%. . .but condensing the bottom of the table 0s and pushing out the top to 200 does a lot of that anyway.
Your problem comes in the actual end result. . .now even assuming the first quarter to third of the table is mostly single lines of zeroes, say to 40 and hits, lets call it from there to 115 at just hits of damage. . .that easily fits into a single page. . .but take a look at an attack table. . .it goes by ones. . .and we're "stretching" that 50% but can't get smaller than 1s.
So another 85 results that basically correlate to critical results. . .which also sounds like a page. . .until you realize that what we're looking at here is Broadsword vs AT12. . .so this is a column, one of five. Assuming the crits are roughly the text size of current crits, that's 4.5-5 pages to fit, even if we underestimate the 0s and just hits at 0.5 page, and lowball the 85 actual crit like results at 4.5 pages. . .it's 5 pages.
I would so buy it, and so use it, and so love it. . .but I don't know if a 5 page long combined attack/crit table for broadsword, preceded by 5 pages for Bola and followed by 5 pages for Club would be everyone's cup of tea. (Damn would it be %$#ing cool as hell though).
I don't think people quite get how crazy it is that RM actually offers via the two roll, two table results, such a vast number of actual variations of result, but it's really mind boggling when you math it out as if it were a single roll table. . .to truly capture it in a single page barbarically cuts the results back to 20%. . .Culling down to two facing pages for a nice spread would be culling variation from current to 2/5. . .40%, or a 60% loss of variability.
Cutting it back to two facing pages, one an attack table, one a crit table, still requiring two rolls would give you as many results as the current game logic does and keep it all on one spread. . .If you could find a sucker willing to do a custom crit table just for each individual weapon, you'd actually extend and multiply the variations of result (since a couple hundred attack tables share say 10 critical tables, if you made it more like X attack tables with X crit tables you'd dupe results less often.). . .course, writing that many crit tables would take a crazy person (or make one).
Really, there's a bazillion variables that go into the attack roll, but like 5 possible modifiers to a crit result in the whole game, all fairly predictable. . .how much game play time does rolling the second, critical roll, take? If you wanted to streamline RM combat, you'd streamline the attack roll mechanism, not the critical, it takes longer to read the crit, react, slap the table, laugh, say a few "Damn. .just damn"s than it does to roll it. . .all the combat time suckage is on the attack side, the crit is like the cherry on the attack sundae.
You could easily drop the two roll method, but even being conservative above, it culls the results back 60% for a spread, 80% for a page, 96% when you cull it back to one column. . .there's a reason why some MERP and HARP people choose to use AL (or moved whole from MERP to RM) . . .it's a huge upgrade in variations of result. . .and a giant cut going in the other direction.
