Stats-Based CPU Sliders [MLB 12 Version]

[nomo17k]

Hi all. I'll be working on a CPU slider set based on the following philosophy:

(1) Adjustments are made for the gameplay to replicate 2009 - 2011 MLB stats as closely as possible. (2011 is weighted twice more than 09 and 10, since that's how players are rated in the default SCEA roster.)

(2) Make the gameplay visually appealing.

I like to have such a slider set myself since my hobby is to create a player and use him in a bunch of CPU vs CPU games and check out how he performs. Because of similar conditions, it's also suitable for MoM and MILFs.

One word of caution is that all tests are done with Vita, so there's no guarantee that this would yield the same results on PS3, although there has been nothing to indicate the same slider set cannot be used for both platforms.

I worked on a slider set based on similar philosophy last year:

It is likely the set will be close to the last year's one.

So far I've run 35 games with the default slider set (except Pitch Speed at 10) to get a set of base-line results. I created a season specifically for slider testing purpose, playing every single game in the schedule. That means in most games aces or No. 2 starters started, possibly reducing offensive output. I'll continue till I get 75 games in, so that aces as well as No. 5 starters from all teams pitch.

Anyways, my early impressions are:

-- Less walks happen compared to real life
-- GIDPs are a bit inflated due to a slightly higher tendency to see ground balls.
-- CPU swings at pitches realistically, but a bit better at putting the ball in play.
-- HBPs and WPs don't happen as often as in real life.

Otherwise, most stats are already very close to the 2009 - 2011 MLB averages. I think things are even better tuned out of the box than in the last year.

On the visual front, I wish to reduce both Fielder Run Speed a tiny bit and definitely Fielder Arm Strength a lot more. I will see if doing so has any adverse effects on generated stats...

Lovely stuff Nomo, it's only March but you are in mid-season form.

Very encouraged by the results you have recorded. Doesn't look like many sliders will need to be altered this year. I, of course, will be editing all the catchers to get more wild pitches, but that's just a personal OCD obsession.

Yes the game at default works pretty well. Very good play variety.

I share the same concern about WPs and HBPs. However, given the walks are a bit down (as usual) we have some leeway in lowering Pitch Consistency slider without worrying about adverse side effects (last year, too many WPs was the problem that caused you to edit catchers).

I doubt we should lower PC slider as much as we did last year, but will see how that increases WPs and HBPs.

Nomo,

As far as arm strength goes, with it one click down, Jeff Francouer cannot make a throw to the cutoff man without it bouncing weakly, even with momentum


This is with maximum effort from the warning track, but i'm pretty sure Frenchy can throw it on a line to home plate from that distance

Thanks for the heads-up. I'm thinking about how much lower I should go with Arm Strength, but visual is quite subjective and it's hard to track something like arm strengths with stats, so it's a kind of grey area.

I have to try myself with long throws to see how they look when I play, but unfortunately I cannot get a lot of games in where I actually play right now... too busy with other stuff, though CPU games run in the background... If previous iterations provide any indication, I think no outfielder had strong enough arm to throw a "laser-beam" from warning track... they were always arch-y, though not necessarily weak.

Again I have to see if things have changed, but with all the stuff the Show gets right, it's actually quite difficult to create a player with very exceptional ability (like Francoeur's arm). So I might need to neglect that if tuning for extreme compromises the overall balance.

What are your thoughts on fielder run speed as opposed to fielder reaction? Which is more important for doubles to gaps and seeing dives?

If you want to fine tune fielder ranges, I think both will have similar effects.

But Fielder Reaction affects both infielders and outfielders, while Fielder Run Speed is much much more important for outfielders, so if I want to adjust only outfielders' range, I'd change Run Speed and leave Reaction to avoid adverse effects on infielders.
