Instructions
Purchase games only from reputable vendors. Street vendors, especially in Third World countries, will often sell pirated games.
Check the box the game came in for any possible grammatical and spelling errors. Pirated games will often have typos and spelling mistakes on the cover of the box.
Avoid purchasing games claiming to have multiple games on one disc with no box cover. Pirated games are often sold as package deals with other games.
Inspect the disc's color and ensure it is not a DVDR. Video games are not printed on DVR discs; they are originally created on DVDs. DVDR discs will have a purple or blue tint.
Inspect the label on the disc. If it appears the disc has a paper label that has been glued on, it is likely a pirated game.
Inspect the box of the game for its creator's trademark and hologram.
