Of course you have to have a spreadsheet! How can we know anything without them??? 
My approach is similar to @DeusIrae. sortable columns of date played, title, score and 2-5 word terse blurb that will remind me what it was. (ie “Finders Commission” was logged as “heist for cats”). Because I try to use a specific rubric documented here, I also log artistic repsonse, tech intrusiveness and bonus (usually +/- 1). I fill it out as I go with completed reviews.
Naturally, since it’s spreadsheeted, I also generate graphs from it. As inevitable as tides, really.
