Making cards in Trading Card Game

So I want to make a Trading Card Game. I've got all the needed rules and graphics, I only have to programme it. I'm wondering if I should make a prefab of every existing card in my game (which is more than 150) or...
Is it good idea to add .txt files with all necesarry informations about card (number for deckbuilder, name, description text, etc.) and only one prefab of a card? Will it change game size and performance? Or maybe store this information in some other way?

And second question about deckbuilder. Should I make a deck.txt file which contains all cards used in the deck (I mean their ID)? Maybe there are some better methods to achieve this.

 

I would certainly use a data-driven approach in this case, that is, have text assets (or an embedded DB or a Google Sheets sheet or whatever you prefer) which define your 150+ cards and all their attributes.

It won't make any difference to the game size and performance, but it will make your maintenance & development much easier. And since that is going to be the biggest cost to the whole project, it is certainly worth optimizing!

 

yeah what he said, about the difficulty of development and maintenance being the real deciding factor here. It'll perform about the same either way, but imagine the nightmare of trying to manage 150 separate card prefabs. What if you ever decide to change what your cards look like? shudder

Definitely go with one general card prefab that gets updated with data about specific cards (eg. change the picture on it)

 

Ok then, I've made Google Sheet (cause my friend could help me with cards ) with all cards' data. So now I probably need a special plugin to connect Unity with this sheet, don't I?

I've found a topic about saving decks: http://answers.unity3d.com/questions/980005/what-is-the-best-way-to-store-data-for-a-deck-of-c.html , so I think I'll use this method.

 

Yep. There are a few assets for that, like this and this. A google search can probably turn up more. I'm afraid I haven't used any of these, so I don't know what's best.
