What game were you playing?? Fallout 3 didn't have *any* tough enemies, and the game's balance was broken and non-existent with DLCs.
new vegas combat is easier than fallout 3, what game are you playing? i played fallout 3 for 2 years and now NV since it came out, combat in new vegas is way easier overall, sure there's a few spots and enemies that are tough but its a lot easier to move around the map world in new vegas than in FO3, way easier, in FO3 there were quite a lot of enemies to deal with, all over the place, enclave patrols, enclave outposts, supermutants all over, talon mercs all over, raiders all over, outcast patrolls all over, tons of deathclaws etc, maybe you didn't play FO3 like i did but nobody is gonna tell me new vegas is harder. ceasers legion are nowhere to be found, nelson and cottonwood cove, thats not very hard combat, and no CL patrols hardly at all, not even any NCR patrols anywhere, geez.
