Which microcontroller is suitable for the system of intellectual games?

Question

Do it yourself

Good afternoon, I need help in choosing a microcontroller for building a system for intellectual games (Brain Ring, Own game, Hamsa). The first option that comes to mind is Arduino, but wouldn’t its power be excessive for the system. which requires:

• Displaying the countdown time on the scoreboard
  
• Playing about five different sounds
  
• Processing signals from several buttons with sufficient accuracy
  

Therefore, I ask you to tell me what other microcontrollers and resources on the network you should pay attention to.
UPD: thanks to all who responded, in the end I chose the ATmega8 DIP28.

Answer 1

STM8 is enough. But it's more pleasant to deal with 32-bit ones, so I recommend STM32. For this task, even a penny STM32F030 will do. On the other hand, if you need to do all this in bulk and even a penny of savings is crucial, you won’t find a cheaper STM8S003.

Answer 2

What do you mean by "with sufficient accuracy"? If you discard this item, then, for example, ATMega8
