The difference is I can frenzy anyone, not just ants and robots, and I can slow down an enemy without the need to hit his leg. Thats why its more tactical. Its not FNV's fault, its kinda hard to compare versatility to a game that has magic. Less rules that have to be obeyed. And I'm not saying Skyrim is better because of this. People are quick to agree FNV is better in certain aspects, but when I mention Skyrim, they are equally as hard headed.
How is that more tactical? It's the same tactic, you can just do it
everywhere. All that means is you don't need to read a specific situation because the tactic is always available. Take two imaginary games: one has an enemy that's weak against fire and an enemy that's weak against ice. The other game has two enemies equally weak against fire and ice. The second game isn't
more tactical just because your fire and ice attacks are useful in more areas. It might mean you can create a more effective single-element character, but character options are different than tactical options.
Can you slow an enemy without using a frost spell? Then how is that different than being unable to slow an enemy without shooting their legs out? You're perform a specific action to generate a specific outcome. That's what a tactic is.
Regardless, I questioned the earlier poster because they seemed to be drawing a distinction between games than enable combat choice versus games that enable quest choice. Skyrim being the former and New Vegas being the latter. But New Vegas
does encourage tactical combat. There's nothing mutually exclusive about this arrangement. You can have a game that is both tactically rewarding and offers multiple quest paths.
