Is 24GB for a SSD card enough?

Is 24GB for a SSD card enough?
I play Sims 3 (have all the games) and will probably start playing 4 when it comes out.

I also play Tomb raider, Dead Island, Far cry 3 and other games like that.

I don't want to have to uninstall and reinstall when i want to play a game i've never had to with the laptop i have now.

And if i do fill up the SSD card can i just play my games in normal storgage. The laptop i'm looking at now has heaps of storgae but not much SSD.

its the lenovo Ideaspad 310p i think

For an external card, yes, BUT for a laptop hard drive no, especially if you hope to play games or store watch movies on it.
