My vote is a bit biased as I've never played 1 or 2. But in my experience if you play the most recent game in a series and like it, the others before it aren't up to snuff. Like they have less sufficient gameplay mechanics that are similar but not alike, or in some cases totally different.
I'm afraid to say that'll mostly be the case, on this forum at least, but anyone is entitled to an opinion, biased or not
But you might be pleasantly surprised if you decided to play its predecesors. Ok the engine is completely outdated, and the interface and gameplay is completely different. But the game mechanics in 1 and 2 are unmatched. Honestly I don't know why Bethesda stripped them down, they were amazing
I just hope it was because they were so busy building the game they there was no time to tweak the mechs, because they would have really enhanced the game, and the fusion of that system in a 3D environment, would have probably made me cry like a little girl
I would put it to anyone to play the previous games, before they judge and try to silence the purists
