Help me make this child rogue a unique build?

[Dannyalcatraz]

I do "max-minned" ( ) PCs all the time...but this one baffles me.

I get why the kid has the gear, but not why he's a rogue. And, given that it's hand me down stuff, I don't see why it hasn't simply been sold for more suitable stuff...stuff that would actually fit his physical stature. ('Cause if he's "small" in the game mechanical sense, some old geezer's breastplate and lance won't really work for him, by rule.)

There was a Fighter variant listed in the d20 (3.x) Unearthed Arcana that allowed a swap of a Fighter's Weapon talents for Rogue Sneak attack dice... a simple fix if it's sneak attack you want from Rogue.

Also, there's the Thug variant (also 3.x, not the Pathfinder one):

The thug is a street fighter, a survivor who learns to mix brute force with a bit of craftiness. He has most of the fighter's strengths, along with some additional skills to help keep him alive on the mean streets. Despite the name, not all thugs are mere hooligans—many are crafty veterans who use their knowledge of the streets to gain an advantage against their opponents. Most thugs are nonlawful, though sometimes gangs of thugs with a lawful streak band together.

[h=4]Class Skills[/h] Add the following skills to the fighter's class skill list: Bluff, Gather Information, Knowledge (local), and Sleight of Hand. The thug gains skill points per level equal to 4 + Int modifier (and has this number x4 at 1st level).

[h=4]Class Features[/h] The thug has all the standard fighter class features, except as noted below.

[h=4]Weapon and Armor Proficiency[/h] Thugs are proficient with all simple and martial weapons and with light armor.

[h=4]Bonus Feats[/h] A thug doesn't gain the normal fighter bonus feat at 1st level. Also, add Urban Tracking to the list of fighter bonus feats available to the thug.
