Pokemon Soul Silver
Reason: This is the best pokemon game i've ever played. the original version introduced so many new, now standard mechanics to the series and has the best soundtrack of the entire series (this I will defend to the death). Also, nostalgia, Silver was the first game I ever owned and I've played it so many time I've lost count. The remake remained true to the original while updating in enough to feel like a new game elevating it above the standard remastering formula nowadays (the inclusion of an item that allows you to listen to the original music sealed the deal for the remake).
Honourable Mention: Spyro 2: Ripto's Rage
Reasons: Spyro 2 is the only game I have ever played that I cannot find a fault in; good story, good characters, fun side-quests that actually matter while providing plenty of challenge for both young and veteran gamers and a score that will forever remain one of my favourites.
