2D sprites in a 3D enviroment, beginner help.

I am in the early pre production of developing my first game.

i want to make a 3d world, but i want to use sprites for my characters and some other environmental items.

i was wondering if this is possible and the level of difficulty in getting this mix to work as opposed to having all my stuff as 3d models.

i have been playing a few games that have inspired the project, i don't want to get into too much detail about it as its a work in progress.

the main game i was playing that really sparked my interest is an older game called Recettear (game trailer https://www.youtube.com/watch?v=YmRN3AFRbZA)

refer to the trailer to get an idea of what i mean with sprites and 3d in one.

if i could get pointed in the direction of some easy to understand beginner tutorials that will help me get started that would be fantastic.
