There is another version of tag that I recall playing as a child, freeze tag. Added a bit more to the game as instead of being 'it' wen touched you were 'frozen' (couldn't move) until someone came and 'unfroze' you (by touching you).
If the person who was 'it' was able to catch and 'freeze' everyone, either the first person 'frozen' or the last depending on what rules were set up, became 'it'.
I believe there is another version called 'stick in the mud'. Basically played the same as above with the execption of how they were 'unfroze'. This was done by climbing between the legs of the person 'frozen'. This was real funny when if the person unfreezing one was caught in that positing.
I've also played theese two games in a pool, much eacher to play 'stick in the mud' in a pool, just don't get caught 'unfreezing' someone
