Yes, but underneath the shallow exterior, lies an ocean of depth. The change from cavalier oblique (Yes, not isometric. Yes, I'm this much of a faggot), turn based, to first person, real time is the only real major difference between 1&2 and NV, this only effects the combat. And lets be honest here for a second, combat was never Fallout's strong suit. Are you really gonna tell me that Fallout 1 & 2 combat was something exceptional?
Just because 1&2's combat are nothing to write home about, it's no excuse to have shitty combat for New Vegas. Yes, it's because of Bethesda's engine that they had shitty combat, but you know what else is lost in translation from isometric, turn-based to first/third-person, real-time format? The freeform interactivity that the originals had. No longer can we solve problems by using our own wits and manually right-click on objects and NPCs on screen and choose what interaction we want to have with them, either 'Look At', 'Use Item', 'Use Skill', etc etc. Instead, in 3/NV's format, you just straight interact with stuff and the game immediately decides what you can and gotta do, and the only choices you had is either you want to do them or not. Having options are still there, like whether or not you want to use your skills or use items, but the game tells you
how much skills you need to pass the check or
what kind of items you need exactly and how much of the items you need, instead of having the players figure it out by themselves, or risk attempting using average skills and let the dice rolls decides the outcome.
And then, there's the shitty lockpicking and hacking minigames. These are one of the worst antithesis to any proper RPG design. Instead of letting the characters skills handle the lockpicking/hacking (and instead, the skills only determine whether or not you can attempt based on arbitrary, rigid threshold), the outcome of whether or not you succeed picking that lock or hacking that terminal is decided by players dexterity as if it's some lockpicking/hacking simulator. You know what's better solution to this problem? Let the characters do the lockpicking/hacking sequence by themselves a la VTMB. Thankfully, a solution exists in form of a mod, called 'Immersive Minigames'.
Also, I haven't mentioned the lost of critical failures mechanic. No longer can you suddenly jammed that lock because your character happened to screw up. No longer can you suddenly lose an entire magazine of your ammo, or dropped your weapon, or suddenly hit yourself in melee/unarmed. There's that weapon jamming mechanic that might happen from time-to-time after reloading because of low-weapon condition, but that's nothing compared to the robust critical failures moments that 1&2 had. There's not even a Jinxed trait in New Vegas, ffs!
Lastly, have you played Fallout 1.5: Resurrection and Fallout of Nevada TC mod for Fallout 2? If you have, then you should understand what I'm talking about. Fallout 1&2, especially thanks to their engine, were the height of cRPG experience from what I know (since, if you haven't know it yet, I'm yet to experience any other RPGs older than Fallout 1&2), and while they were made to emulate P&P experience, 1.5 and Nevada proven that with the engine, they could achieve much more. We can argue that 1, 2, and NV were quite on par based on overall quality of each, but 1.5 and Nevada beat them all by a thousand miles.
Regardless, NV is the closest Fallout will ever get to the originals. It's Fallout 4 and Fallout 76 type shit from here on out. Be fucking glad NV happened.
Nah, this argument just reeks of that exact same argument repeated by Bethestards saying how we should all be glad Bethesderp 'popularized' Fallout with Fallout 3. I'm not glad NV happened, I'm sad. We don't get to see how Van Buren is really going to be, and New Vegas only reminded me of glimpses how it could have been. Not to mention the spirit of the original Fallouts lived on thanks to 1.5, Nevada, and couple other fanmade TC campaign mods, it's kinda bittersweet really. It's like listening to Maybe, except yes, I think of them, when I'm all alone with New Vegas. Yes, I sit and sigh, wishing Van Buren is near (or real, for that matter). Yes, I asked 1&2 to come back again, only to have 1.5 and Nevada whispered, 'Maybe...', to my ear.
