T2 is a hard game for me to rate because it has a lot of nostalgic value to me. I picked this game up because I had a blast playing it in my college years. There was a "beater" T2 at a laundromat that I couldn't stop playing. Perhaps it was the simple approachable ruleset? Perhaps it was theme? Either way, there is something about this game that keeps me coming back, even as a now-more-experienced player. I have my game set STEEP with a wide open outlane. It is freshly waxed with new rubbers and plays fast. I enjoy T2 because it is a fantastic game to practice ball handling and nudging skills on. If your nudging game is on, you can really have some long ball times and fast play. If you are not feeling "on" the game will punish you for it with bricked shots, SDTM drains, and outlane drains. I love the Super Jackpot shot, it is utterly satisfying when you can time that cannon shot just right while keeping the other balls in play. There might not be a ton of variety, but T2 does a whole lot with a fairly basic playfield.
As far as quality, I believe T2 is a "transition game." Its layout is simple, but effective. As others have said it is reminiscent of a system 11 game as far as complexity. The cabinet art is pretty good, but not breathtaking. I think the playfield has a great art package, however simple. It is well lit, has nice lines, and is finished off by a neat pair of Terminator hands over the slingshot. The DMD animations are solid, but lacking when compared to games like Twilight Zone or AFM. However I think the package works great as a whole. The sound can be very engaging when turned up with intense gun noises etc. as the ball flies around. I'm sure an upgraded speaker kit would do very well here, but the stock sound pleases me. What I love most about T2 is the light show!! There are no exposed flashers(flasher domes) in the game, but there are many well placed flashers across the playfield. When you do something impressive, you get rewarded with a great light show. T2 might be "simple", but you can't help but get into the game with the intense sound/light show combination. One of my favorite moments oddly enough is post-game when the GI goes dark and the flashers are flashing rhythmically to the T2 theme. Be sure to give T2 a few plays in a dark room and see what I mean! Even with the standard lighting, no LEDs, the lighting is very stimulating. Very well done Williams. As a whole, Terminator 2 is a solid title if the theme agrees with you.
As a bonus, the game is not intimidating to service. I was able to dismantle and reach every area of the playfield with not much trouble for cleaning and rubber replacement. I am confident to tackle routine maintenance on T2, whereas on Twilight Zone I am a bit more nervous to "get under the hood."
