But it exists solely as a "game balance" issue and makes zero sense for what the mod actually is. It's like SMG's in Half-Life: SMG's do less damage per bullet than a pistol does while using the exact same ammunition. It's game balance that's actually detrimental to gameplay. Same here.
If we were going to be using the game balance card, then Emotitoys should be priced much, much higher than the software package which provides the same benefit. But they aren't, because of some real world sense here: Emotitoys are hardware that can be broken or rendered obsolete and thus need replacing; the software can be copied and upgraded with little effort and thus costs more.
Honestly, enhanced articulation is such a good mod (even if one uses the ridiculous limitation) that it would make sense that anyone who can remotely afford it would buy it. Hell, I'd buy the thing if it were real, and I wouldn't mind going into debt for it, as one of the side effects of the mod is to cure or prevent arthritis. That by itself makes it a "must have" mod. Along with synthacardium and pathogenic defense augmentations, a body will live much healthier for much longer.
I won't even talk about the brain enhancements, as they would be auto-include for anyone considered skilled labor or an executive. (Seen the sleep-regulator enhancement? Yeah, it's just that good.)
