Is it easy to develop games like Project IGI and Max Payne?

I'm new to this forum but i've always been a huge fan of games.

I grew up playing games mostly Max Payne, Project IGI, Road Rash, AOE, COD, Battlefield 1 and 2, NFS Underground and Most Wanted, Brothers In Arms and many more.

But i kinda liked Project IGI and Max Payne. Those both were the classic games of all time, the graphics were crisp and clear. I just loved playing them both!

So my question is:

Is it easy to develop games like Project IGI and Max Payne?
How many people do you think can work out on those both games?
How much time does it consume to make that games?
Which coding language is appropriate to develop those both games?

I want to have that classic graphics look unline today's more realistic graphics.

 

here's some short answers:

1. No.
2. Depending on how devoted and skilled those people are and how much spare time they have.
3. A loooot if you want to make it right - not so much for prototyping though.
4. Any language will do, but personally, I'd suggest C# because it's much more universal than Unity script and also allows you to develop on platforms other than Unity.
5. I'm not making a lot of friends saying that, but I'm absolutely convinced, that graphics are highly overrated. They should be good but seldomly have to win contests to make for a good game.
