Final Fantasy XIII £10 New

Don't hate me I have never played a final fantasy game in my life and saw it today down morrisons I was not gonna bother until I saw it for £10 I was like WTF that's cheap so here is a few things I need to ask:

Is it worth the £10 I paid?

If you know of the game last rebellion is it like that?

How long is completion time?

Would I enjoy it if I have never played a FF game before?

Thanks - I can always sell for £10 so won't loose XD

Is it worth £10? Yeah

Is it like Last Rebellion? It's a lot better. If Last Rebellion is your only taste of Turn based tactics games then will be brilliant. FFXIII isn't a bad game on it's own - but compared to really good TBT games like Shadow Hearts 2, Xenosaga 3 or Persona 4, it's certainly lacking.

Completion time? 20-30hrs without extra side crap - the retry on the battles is pretty generous, so there's not too much - I died, now I gotta replay that huge section again -

You'll enjoy it more for never having played an FF before.
