I think it's a con. It states that all games on the CD are shareware or freeware.
If it is then how come he charges £12 - this is far more than would be expected for reasonable costs in copying the CD - remember you are not allowed to charge far more than the cost of CD & duplication when making shareware compilations.
Why does he show pictures of obvious commercial games - Ghosts 'n' Goblins, Street Fighter etc....? if he lists as shareware. Either he's making money of old commerical games, or he's lying and these games are not in there.
Why pay for all of this when it can be downloaded ?
