Some people are talking of realistic style game play like having no position coordinates and no compass, so I'll add my opinion on realistic size advantages and disadvantages.
Tiny toons already have two built in advantages...they're harder to hit because of hitbox, and their size allows them to stand/hide behind smaller rocks and trees without detection. That should be all they get in advantages.
I've never had any difference in ability to hit anyone IRL depending on their size. But I guess the game requires smaller hitboxes for smaller toons.
The ability to hide is dependant on blending into surrounding, as well as lack of movement....thats why snipers wear guilly suits and move extremely slow towards their objective, then remain still once in position.
Smaller toons should get less max strength, as less mass=less bulk. This would allow them to put extra stat points in agility if wanted, but no game given advantage to agility should be given.
A smaller toon would be able to hit less hard than a large, and when recieving a hit from larger toon, the smaller would have less mass to absorb the hit. This would be mimiced in game with difference in strength stats.
Agility should be reduced actually for smaller toons, if weilding a weapon, as the weapons are large and would be more cumbersome for smaller toons.
Reach of course would be reduced for smaller toons. That is why larger boxers are favored when considering reach advantages.
No run speed advantage should be given, as they have to actually run twice as hard as a big toon to reach same destination because of a shorter stide length.
There was a reason the Philistines sent out Goliath...the largest and most feared of their army. David beat him in spite of being smaller, not because of it...and a projectile, not size gave the win.
There is a reason taller people win marathons and excell in track and field, as opposed to shorter.
There is a reason smaller people are ususally the sidekick, not the hero.
I've never known anyone who wishes they were smaller as opposed to being taller.
So...in closing, I dont understand why people want to create smaller toons, unless they want to mimic their real life self, or just like the advantages other games gave to small toons in combat and hope to have that here.
ALL the stats will have benefits to certain skills when raised, and of course lessen advantages if lowered....with limited points for stats....maybe that should be ultimate decider in most abilities.
If you dont agree with these thoughts on size vs abilities, please say so, but please, give a reason why.
