It is worth the 2 yr age gap and sibling squabbling to avoid this... I think... 
The worst stage was when DS1 was 4 (so DS2 was 2 and a bit young for him) and I dreaded the words "play with me!". He'd have a vision of exactly how to play in his head, that I invariably could not telepathically match, so he'd throw a "tantrum", but he'd still have the concept of me playing with him in his head and I wasn't allowed to not play with him either... until I cracked, threw a tantrum too and stropped off 
It turns out that that was his ASD at play. He struggled with other children too and didn't really crack playing WITH children rather than alongside until about 5-6. It's still a skill he can struggle with.
I can do structured games like battle ships, frustration as long as the rules are respected.
I can do outdoor play.
I chat to them.
I endure hours of minecraft/ weapons of WW2 based discussion.
I had halcyon dreams of crafting with my precious darlings and I used to love craft... but the reality of 5 minutes setting up, 30 seconds crafting, 3 minutes body painting and 30 minutes bathing children and cleaning up a zone of post-apocalyptic proportions was more than I could endure.
They do get a lot from me (or Scouting. Scouting is amazing for redressing my shortfalls
), but they do get the space of independent play too, and that is a very important skill.
Until the last couple of decades, most of the time children would have been turfed out into the street to play anyway. There never was an expectation of mothers (because let's face it, it is mothers and not daddy who had a long day at work and just needs to come in for a bit of a rumpus at the end, and play a bit of football at the weekend
) to play and constantly entertain the children anyway.
