Which laptop should I buy for under for £1000 - for university and light gaming?

I want a laptop for under £1000 that is good for university. It should be able to cope with games like Runescape, Sims, TF2, Overwatch, Minecraft (I don't play all of these - just examples lol). It should have a decent battery life, enough space for a few games as well as many documents, and also it should last a relatively long time (I'm not starting uni till next year). Not too keen on Macbooks and not bothered about having a touch screen.

I've researched a bit and I think the one I'm most keen on at the moment is the ASUS ZenBook UX330UA. I wish I could get the Dell XPS 13 but it's too expensive! I'm a bit confused though, because on Amazon there are two versions of this ASUS laptop: FB100T and FC093T - what's the difference? One of them is £100 cheaper and I don't want to spend an extra £100 if it isn't needed.

Here are the links to the two of them. Is the £100 more one more expensive because of it's i7 intel core instead of i5 intel core? Honestly, I hate all these numbers and words I don't understand properly lol despite doing a bit of research.

So does anyone else think this ASUS Zenbook would be good? Or has anyone got any other ideas?

And this is probably the right choice pushing the battery life to about 4 hours average.

You pay a premium in a below 15.6 inch.
This one is interesting if gaming is not important

Audio is an issue

There are nice laptops in a 15.6" that cost less, but since looking at 13.3, I think 14.1 is better at college but both are more portable than 15.6.
