Tom and Jerry (Morning Star Multimedia/Majesco, 1999)
A boring standard platformer. The only thing remotely interesting about it is that I took this screenshot moments before the thing I'm standing on, which is apparently a manhole cover, suddenly shot up into the sky and killed me instantly. That makes you start the level over from the beginning, and is also terrible design.
Tom and Jerry: Mouse Hunt (Conspiracy Entertainment, 2000)
It's a race to collect 15 mice, but it's not really fair because there are way more hazards for Tom than Jerry and only Tom's mice can be removed from the goal. That makes sense thematically, sure, but it does not make for a fun game.
Tom and Jerry in Mouse Attacks! (Warthog/NewKidCo, 2000)
Another basic platformer, although this one at least has special items and doesn't OHKO you with floor traps. Unfortunately, the way you get special items is by winning a timed sliding block puzzle challenge while listening to painfully bad music.
Tomb Raider (Core Design/THQ, 2000)
I could talk about how this game's plot is historical nonsense and how it doesn't know the difference between "its" and "it's", but I'd rather focus on their decision to make Up jump instead of using B at all, and also to have three seconds of music at the start followed by only using sound effects. It feels horrible to play because jumping is so awkward, looks terrible, and doesn't sound like anything.
Tomb Raider - Curse of the Sword (Core Design/Activision, 2001)
They did at least manage to get through the intro without any typos or statements that made it clear they know nothing about their theme, but nothing else is any better. The music still cuts out after a few seconds and it still controls like garbage.
Tonic Trouble (RFX Interactive/Ubisoft, 2000)
I'd call this a Rayman ripoff, except that it's also from Ubisoft. It's apparently a remake of an N64/PC game they released the year before to mixed reviews, but it fared even worse. I don't think it's possible to get past these ducks without taking damage, because you can only barely jump higher than them once you're in the water and you certainly can't jump longer than they are.
Tonka Construction Site (Sunset Entertainment/TDK Mediactive, 2002)
You use heavy machinery to do construction tasks around construction sites. It's very basic, but it probably would've been fun for kids.
Tonka Raceway (Morning Star Multimedia/Hasbro Interactive, 1999)
A really zoomed-in MicroMachines-style racer. Unfortunately, the tracks are way too narrow for four racers, and everyone is constantly crashing into each other or hitting the walls instead of racing. They couldn't possibly have known what they were doing 22 years ago, but in 2021 it can also be seen as a great Ever Given simulator. If you manage to get yourself turned sideways, you jam up the entire track and no one can get by.
