I agree with the previous reviews that James Ghetty is a fine and versatile character on a good value: strong influence, a back-up stud and an emergency mad-scientist. A small but important disagreement with a previous review however: James Ghetty can only pay for Shootout Abilities, so his trait can't help pay for boosting your hand rank with Force Field. Same thing applies for paying for It's Not What You Know..., Cheatin' Varmint and so on. He can only pay the printed (bottom left corner) cost of "Shooutout" abilities (so no using it to pay for the previously mentioned reacts/resolution plays). As noted in the collected rulings this means he can't pay to return An Accidental Reunion back to your hand.
Still a fun card, but make sure your opponents don't make his trait stronger than it is by using the ghost rock more flexibly than intended!
