Do I need a landing page for mobile game offers?

Looking at getting into media buying specifically doing cpa offers with mobile games.
I was wondering if it is a good strategy to direct link from your banner to the app store and skip a landing page for game offers? Which makes sense to me as I feel like landing pages are kinda awkward on mobile especially for something that is free like a game.
Also would you guys suggest doing single offers or smart-linking for a beginner? I'm trying to be conservative with my funds and not waste them away if I don't have to.
Thank you in advance for the help!

All the ads I have seen, they just redirect to play store, app store. None have redirected to a landing page.

SO yeah, just ads -> play store/app store.

You could experiment with banner ads, video ads etc.
