Honestly, that one looks easy.

The swing and monkey bar will just be attached by bolts at the top (and probably per assembled otherwise) and the Aframes look pretty simple.

I'm not sure if starting to put it together would help. For instance, it lookalike the Aframes slides into the top and you bolt the cross bar on - so you can't really do it beforehand.

Maybe get it out and see how the instructions are and make sure all the bits are there and work out what you can per assemble.

I put a similar one together for a friend recently and it took about 2 hours.

Good luck!
