For example, should I allow the vote of Joust, even if Joust 2 is forbidden

Here follows the complete list of my "doubts" :
Joust ( joust 2 already used )
Super Street Fighter II ( Sf2 already used )
Spelunker 2 ( spelunker already used )
Puzzle Bobble 2 ( PB already used )
19xx - The War Against Destiny , and 1941 ( 1942 already used )
Metal Slug 2 ( mslug already used )
Wonderboy 3 ( wonderboy already used )
Another thing, a little bit different :
Time Pilot Time Pilot 84 are not clones, but are very similar. Can I accept both votes ? Same case for 19xx and 1941

Thanks for telling me your opinions.
Cheers.
