Ninja Warriors is a horrible, awful pile of shit on the Duo. Seriously, what the f*ck happened? Taito really dropped the ball here. The coolest thing about the game is that you can, from the options menu, choose between 13,957 colors for your character's uniform.
Don Doko Don is a Bobble Bobble clone from.... well, the makers of Bubble Bobble. I'm not sure what they were going for here. DDD lacks most of the charm that made the BB series so great. There's nothing horrible or awful about Don Doko Don but everything is very, very middling. The epitome of mediocre. It's almost like Taito sat down and said, "Bubble Bobble is just too good. We've really outdone ourselves. Let's scale it back a little bit in every department and make something the everyman can relate to."
Tiger Road is a Turbo game developed by someone (AiCOM maybe?) loosely based on an arcade game called Tiger Road, developed by Capcom. The general theme and gameplay elements are similar, but I'm not sure I'd call it a port. It's more like a re-imagining or a spinoff. It's a fun game, I always had a great time with it. People sometimes complain about hit detection issues but I never experienced anything in this department that deterred me. It's certainly no Impossamole. Tiger Road on the Duo has a lot of character, I'd recommend it over the other two, easy.
I haven't played the Tiger Heli sequel/prequel/whatever.
