"They don't build them like that anymore."
The graphics have, of course, aged somewhat, and those used to modern HD might not appreciate the 3D-imitative character sprites, or the flat crowd, but, for me, the suit the flow of the game perfectly, and add a level of charm - the serve to show the type of player you are using (big and strong, or small and fast), and they have a nice, retro feel to them that will make you think it's the 1990s all over again.
As for sound, who could forget the commentary? With such classic lines as "Digging like a demented mole" and "That'll put him into ward 4" followed by "I should hope not... that's a maternity ward..." Outside of commentary, the game delivers satisfying sounds from big hits and such, and there is a level of crowd noise which works appropriate to what happens on the pitch (the volume swells after scores).
But it's the gameplay that really makes Jonah Lomu Rugby great - the pace and power that you feel it has. Controls are hugely responsive, and at no point will you feel the game has 'cheated' you in the way other sports games (such as Rugby 08) might - you are really in total control. The difficulty curve is perfect - you define it yourself, as the difficulty depends entirely on which teams you choose. This can range from beating down lightweights like Hong Kong, or Ivory Coast, to taking on the big guns like the All Blacks, or Australia (the final 'Classic Match' requires the player to beat New Zealand as Japan!)
In terms of longevity, there is plenty to do here. A great place to start is the Tournament mode, which offers a range of Cups for different terrirtories. Completing these unlocks other tournaments to beat, which feature different special teams. If you do get bored of all the tournaments, then the 'Classic Match' mode allows you to re-live various World Cup matches, sometimes trying to change what happened. If you actually manage to finish both of these modes, then you can still play 'friendly' matches against the computer, or (and this is an area in which the game really shines) you can play with or against up to 3 other human players.
Jonah Lomu is, overall, a fantastic sports game, which any fan of the genre should enjoy.
