For me, at least, “like D&D” can mean a lot of things. There are some games where you can tell their starting design point was just D&D, and everything else is either a tweak, a replacement or an addition. It doesn’t matter what gets changed, so long as it’s obvious what it was changed from.
The Fantasy Age system does a lot of things differently, but you can still tell they were working with D&D as their base design. You roll 3d6, but you still add your ability (and a skill bonus if you have the skill) and compare it to a target number.
