I did, however, play quite a few games that were released before 2015. Here are some words about the ones I enjoyed the most.
999 (DS)--Everyone seems to love this Chunsoft-crafted visual novel. So why did it take me so long to play more than a couple of hours of it (I've owned a copy for years now)? I wish I could tell you. What I can tell you is I'm thrilled I broke through that self-imposed barrier earlier this year. This time around, not only did I finally get past 999's opening chapter, but I finished each and every one of them--multiple times over. In fact, I eventually encountered all of this tense title's many endings and devoted more than 20 hours to doing so. Hopefully I'll find Virtue's Last Reward, the Vita version of which I just acquired, just as compelling.
Alien Syndrome (Game Gear)--I turned up my nose at this arcade port for years due to what I considered (at the time) to be its subpar visuals. Truth be told, I also wasn't all that interested in its seemingly brainless gameplay. For whatever reason, I put those initially negative (not to mention ill-informed) impressions behind me and gave this iteration of Alien Syndrome another shot a month or so ago and ended up having a blast. I'm still not a big fan of its boss battles, which are more than a bit claustrophobic on the Game Gear's tiny screen, but the rest of it this creepy run-and-gunner's content is surprisingly enjoyable when you give it a chance.
