The Assembly's Economy Committee is calling for lessons to be learned in it's report The Price of Gold.
It noted that London 2012 kept its promise to evenly spread tickets across its five price categories, but stated that each category price "varied between sessions and, for a large number, were skewed towards the high end".
"For many ordinary people, the lack of available affordable tickets for certain sessions meant there was little chance of them being in the crowd to see their sporting heroes win gold.
"Given that ticket sales massively exceeded their target, this was a missed opportunity to reward those taxpayers who funded the Games and inspire a generation to participate in sport.
"We must learn the lessons from London Olympics and Paralympics if we are to host future sporting championships successfully and build on the amazing public support and goodwill demonstrated during the summer of 2012."
