Both Rogue Trader and Deathwatch have two options for generating a characters characteristics, by randomly rolling the dice, or by a point buy system. For both of them the choice is between a 2d10 roll for each characteristic, then the option to reroll one of them and take the second roll. If you go point-buy, both give players 100 points to spend with a max of 20 in any characteristic.
The difference between them is that RT claims the characteristics will be better with point-buy, DW claims they will be worse. Which one is correct ?
