Currently playing Fallout New Vegas. Not on GoG, but it should be because it's fairly faithful to the old games.
Whilst it is limited by the Gamebryo engine, it is still a fairly enjoyable RPG that is full of references and uses background from the older entries in the series.
The dialogue is top notch, the world is well built, and whilst the gunplay does feel rusty, it is still satisfying enough, and besides, Fallout was never solely about combat anyway.
The Hardcore mode truly changes the game, and makes the task of surviving in the wasteland as hard as it should be...well, early game at least. I find that late game, your character becomes an unstoppable juggernaut, carrying 100s of kilos worth of ammo, weapons and supplies, and having enough skill points to hack, lockpick, built supplies and fast talk his way out of every situation. There was something like that in Skyrim, and I hated it. Fortunately, there are mods to remedy this, though it would have been nice if the game didn't require them.
All in all, it's a good entry into the Fallout series.
